Reversible splenial lesion syndrome (RESLES): Two patients as study cases.

Radiol Case Rep 2022 Oct 30;17(10):3635-3638. Epub 2022 Jul 30.

Department of Radiology, Mohammed VI University Hospital, Faculty of Medecine, University Mohammed First, Oujda, Morocco.

Reversible splenial injury syndrome (RESLES) is a rare clinicoradiological entity that defines a reversible lesion in the splenium of the callosum in magnetic resonance imaging. RESLES may be of infectious iatrogenic or metabolic origin. We report 2 cases of drug induced RESLES in our training. The presence of an isolated lesion of the corpus callosum in a context of polymedication by psychotropic drugs and the regression in less than 4 weeks suggests a toxic origin, in particular medicinal. The pathophysiology of these reversibles lesions of the splenium of callosum is not very clear, most often it is a phenomenon of vasogenic edema that is evoked, the clinical symptoms are very varied and nonspecific, and the prognosis is generally good in the absence of underlying disorder.

A rare case report of an adult with down syndrome and gallbladder cancer.

Ann Med Surg (Lond) 2022 Jul 20;79:104025. Epub 2022 Jun 20.

Department of Hepato-gastroenterology, Mohammed VI University Hospital Center, Digestive Disease Research Laboratory, Medical School, Mohammed I University, Oujda, 60000, Morocco.

Introduction: The most frequent malignancies observed on adult with Down syndrome are lymphoblastic and myeloblastic leukemia. The incidence and the relationship between gallbladder cancer and Down syndrome is unknown.

Case Presentation: We report a rare case of a 25-year-old male with Down syndrome who consulted to the emergency because of deterioration in overall health associated with post-meal food vomiting, abdominal distension and diffuse abdominal pain. CECT scan reveal suspicious locally advanced parietal tissue thickening of the gallbladder, associated with peritoneal carcinosis, and a bilateral massive pulmonary embolism, in addition to a large bilateral pleurisy and moderate pericardial effusion. The patient died three weeks later.

Discussion: Solid tumors are rare among population with Down syndrome, especially gallbladder cancer.

Main Risk Factors Are: cholelithiasis and gallbladder abnormalities, which are frequent in these patients. Management of this lethal disease depends on precocity of diagnosis. For this we suggest an abdominal ultrasound in children with DS to screen previously cholelithiasis and prevent this fatal cancer.

Conclusion: Some Authors found that the rate of gallbladder disease especially cholelithiasis, was 25% among Down syndrome group, compared to 4.5% among the control group (p = 0.002). We suggest that cholelithiasis is the main risk factor of gallbladder cancer in this population. However, other prospective studies should be accomplished so as to confirm this outcome.

Pericallosal lipoma: A case report.

Radiol Case Rep 2022 Sep 24;17(9):3094-3096. Epub 2022 Jun 24.

Department of Radiology, Mohammed VI University Hospital, Faculty of Medicine and Pharmacy, University Mohammed First, Oujda, Morocco.

Pericallosal lipoma or lipoma of the corpus callosum is a rare congenital brain malformation that can be associated to dysgenesis or agenesis of the corpus callosum. It is usually asymptomatic, but can be revealed by epilepsy, paresis, paralysis, dementia, or headaches. CT and MR imaging play an important role in making this diagnosis. Lipoma of the corpus callosum can present as 2 different types: tubulonodular and curvilinear. Tubulonodular lipomas are the most common morphology. We report a case of 60-year-old woman, admitted for a seizure following a head trauma that benefited from a head CT revealing a curvilinear lipoma of the Corpus Callosum.

Chronic lymphocytic leukemia, a rare cause of spontaneous rupture of the spleen.

Int J Surg Case Rep 2022 Jun 16;96:107315. Epub 2022 Jun 16.

Department of General Surgery, Mohammed VI University Hospital, Faculty of Medicine and Pharmacy, Laboratory of Anatomy, Microsurgery and Surgery, Experimental and Medical Simulation (LAMCESM), Mohammed Ist University, Oujda, Morocco.

Introduction: Spleen Spontaneous Rupture SRS is a rare phenomenon in which the spleen ruptures without associated trauma. This pathology is rarely caused by Chronic Lymphocytic Leukemia.

Presentation Of The Case: We present a case of a 59-year-old male patient with chronic Lymphocytic Leukemia, who was admitted with an acute abdomen whose clinical and paraclinical examinations revealed a spleen spontaneous rupture. The treatment consisted of a splenectomy.

Discussion: Spontaneous spleen rupture was first described by Rokitansky in 1861 and mentioned in many cases since, the common causes of non-traumatic Splenic rupture include myeloproliferative diseases, vasculitis, and infections. However, Chronic Lymphocytic Leukemia (CLL) remains an obscure cause of splenic rupture that requires unique attention. The diagnosis of splenic rupture should be considered in all patients with hematologic malignancies presenting with abrupt onset of abdominal pain, hemodynamic instability, or acute anemia. The choice between conservative treatment and splenectomy depends on different variables: the etiology of the SRS, the hemodynamic stability, the amount of packed red blood cells transfused. Thus, an interventional approach can be advocated for a spontaneous splenic rupture over nonoperative management. Splenic embolization can provide patients with the advantages of both operative splenectomy and conservative management. The mortality rate from SRS is 12.2 %. Neoplastic pathologies were most significantly associated with fatal outcomes.

Conclusion: The high mortality rate seems to be mainly related to the delayed diagnosis and/or the severity of the underlying pathology. Given its seriousness, it requires a rapid diagnosis and adapted management.

Retroperitoneal desmoid tumor in a patient with familial adenomatous polyposis: A case report.

Radiol Case Rep 2022 Sep 17;17(9):2910-2914. Epub 2022 Jun 17.

Department of Radiology, Faculty of Medicine, Mohammed VI University Hospital, University Mohammed First, BP 4806 Oujda University 60049, Morocco.

Desmoid tumors are benign fibroblastic neoplasms, with locally invasive features and a tendency of recurrence. They are considered an aggressive non-metastatic fibromatosis. The retroperitoneal location is extremely rare. Their exact mechanism of occurrence is still controversial, but could be related to a genetic predisposition, hormonal factors or traumatic factors, including surgery. This entity faces management difficulties due to its rarity, the variable circumstances of its discovery, and the non-specific clinical manifestations. Their sensitivity to chemotherapy and radiotherapy is limited and surgery remains the only curative treatment in symptomatic cases, however observational waiting could consist the most appropriate management in selected asymptomatic patients, moreover it could avoid unnecessary morbidity from surgery or radiotherapy, which makes the management of this condition a multidisciplinary decision and should be adapted to fit the patients individually. We report a case of a retroperitoneal desmoid tumor in a 31-year-old woman with a history of familial adenomatous polyposis, through which we will discuss this extremely rare neoplastic entity.

Novel homozygous inactivating mutation in the luteinizing hormone receptor gene (LHCGR) associated with 46, XY DSD in a Moroccan family.

J Pediatr Endocrinol Metab 2022 Jun 6. Epub 2022 Jun 6.

Department of Endocrinology-Diabetology, Mohammed VI University Hospital Centre, Faculty of Medicine and Pharmacy, Mohammed I University, Oujda, Morocco.

Objectives: We present the first cases of two male brothers with Leydig cell hypoplasia secondary to a novel mutation in the LHCGR gene that has never been described before.

Case Presentation: We report the case of two brothers with Leydig cell hypoplasia (LCH) type II caused by novel homozygous inactivating mutation of the LHCGR gene, located in exon 10 in c 947 position. The two patients presented at 11 years 7 months and 1 year 6 months, respectively, with abnormal sexual development, micropenis and cryptorchidism. Genetic analysis revealed a homozygous deletion of approximately 4 bp encompassing exon 10 of the LHR gene in the two brothers indicating autosomal recessive inheritance. An hCG stimulation test induced testosterone secretion within the normal range. Subsequently, a treatment with enanthate of testosterone was started, with an increase in the length of the penis.

Conclusions: Leydig cell hypoplasia is a rare form of disorder of sex development. We report the occurrence of a new mutation of the LHCGR gene in two Moroccan brothers in whom the clinical features and the molecular diagnosis were correlated.

What Lies Behind the Cannonball Pulmonary Metastases: Hodgkin's Lymphoma?

Cureus 2022 Apr 21;14(4):e24351. Epub 2022 Apr 21.

Pediatric Hematology, Faculty of Medicine and Pharmacy/Mohammed VI University Hospital, Oujda, MAR.

The cannonball pulmonary appearance is hematogenous dissemination of various primary tumors but rarely a Hodgkin's lymphoma, a disease that most commonly manifests with lymphadenopathy, often affecting the mediastinum and supraclavicular or cervical lymph nodes. To date, to the best of our knowledge, no case has been reported where the investigation of a cannonball pulmonary appearance led to the diagnosis of Hodgkin's lymphoma. Hence, in our case report, we attempt to highlight the uncommon presentation of this disease in a 14-year-old girl who initially presented with dyspnea before her chest x-ray revealed a cannonball pulmonary appearance, which was later linked with Hodgkin's lymphoma after performing a biopsy of her axillary node.

A rare case report about a congenital adrenal hyperplasia by 21-hydroxylase lock in its pure virilizing form discovered in adolescence.

Ann Med Surg (Lond) 2022 Jun 28;78:103673. Epub 2022 Apr 28.

Department of Endocrinology-Diabetology, Mohammed VI University Hospital Centre, Faculty of Medicine and Pharmacy, Mohammed I University, Oujda, Morocco.

Introduction: Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency is an autosomal recessive disease. The diagnosis of the classic virilizing form must be made at birth.

Case Presentation: We report the case of a 16-year-old female patient, who consulted for primary amenorrhea and absence of breast development, in whom the clinical examination found a male morphotype, signs of virilization with a peniform hypertrophy of the clitoris. Pelvic ultrasound confirmed the presence of the uterus and ovaries. A syacthen test on 17 hydroxy-progesterone was performed confirming the diagnosis of congenital adrenal hyperplasia by partial 21-hydroxylase deficiency. The treatment was based on hydrocortisone and spironolactone with a decrease in hairiness and a breast development after 3 months.

Discussion: The principal aim of the management at adolescent age is to block hyperandrogenism and to prevent or manage the complications of classic form and its treatment. The treatment must be completed by a feminization surgery which constitutes a great challenge given the necessity of participation of a gynecologist and a pediatric surgeon experienced in the surgery of anomalies of sexual development.

Conclusion: This rare case of anomaly of sexual development discovered at an adolescent age with all the obstacles and difficulties of its management allows to put the point on the necessity of a good clinical examination at birth and the early management of any anomaly of sexual development.

Fatal outcome of posterior reversible encephalopathy syndrome (PRES) in a lupus nephropathy patient: A case report.

Radiol Case Rep 2022 Jun 19;17(6):2215-2219. Epub 2022 Apr 19.

Department of Radiology, Mohammed VI University Hospital, Faculty of Medicine, University Mohammed First, BP 4806 Oujda University, Oujda 60049, Morocco.

Posterior reversible encephalopathy syndrome is a rare underestimated condition, that generally complicates a rise in blood pressure in an acute setting. This entity has been increasingly identified in patients with systemic lupus erythematosus disease. PRES is challenging to diagnose seeing as it presents with nonspecific neurological symptoms, such as head-aches, confusion, seizures, visual changes or a coma, and can mimic neuropsychiatric lupus. Imaging plays a necessary role in confirming this diagnosis, as it is characterized by vasogenic edema of the posterior white matter, in which the distribution is bilateral and symmetrical. Although this syndrome is rare, early diagnosis allows a prompt treatment and therefore a favorable outcome. We present a case report of PRES in a 14-year-old female previously diagnosed with lupus nephropathy, who presented to the emergency department with seizures and uncontrolled hypertension, that was unfortunately not reversible is this patient.

Cervical myelopathy involving os odontoideum with retro-odontoid cyst and atlanto-axial instability: A case report.

Radiol Case Rep 2022 Jun 8;17(6):1982-1985. Epub 2022 Apr 8.

Radiology Department, Mohammed VI University Hospital, Faculty of Medicine, University Mohammed First, Oujda, Morocco.

Os odontoideum is an unusual anatomic variant of the dens of C2 defined as an independent ossicle separated from the axis; the etiology is a topic of debate, with investigative studies supporting congenital and traumatic origins, clinical manifestations vary from asymptomatic forms, underlying C1-C2 instability to compression of the spinal cord or vertebrobasilar ischemia. We report a case of a patient with a history of minor trauma 5 years ago, she suffered from neck pain. The clinical examination was normal. Radiological examination including X-ray, CT, and MRI showed cervical myelopathy involving os odontoideum with C1-C2 instability and compressive retro-odontoid cyst. Imaging has an important role in the management of os odontoideum, from diagnosis to therapy.

Presacral ganglioneuroma in an 8-year-old child: case report, and literature review.

Radiol Case Rep 2022 Jun 4;17(6):1866-1869. Epub 2022 Apr 4.

Vascular Anomalies Research Unit, Medical Science Research Laboratory Mohammed VI University hospital, faculty of Medicine, University Mohammed first, Oujda, Morocco.

Ganglioneuromas are benign tumors of the sympathetic nervous system, rarely found in the presacral region. In this study, we report the case of presacral ganglioneuroma in an 8-year-old girl, who complained of abdominal pain with diarrhea and abdominal distension. Ultrasound showed a large hypoechoic pelvic mass complicated by right ureter hydronephrosis. the CT and MRI confirm the presence of a presacral tissue mass with heterogeneous enhancement after contrast injection. The child underwent a complete surgical resection, and the anatomopathological study returned in favor of a ganglioneuroma. The presacral ganglioneuroma is an extremely rare tumor in that only twenty cases have been reported in the literature. 3 of which were less than 8-years-old. Through our case, we will review the epidemiological, clinical, radiological and therapeutic characteristics of this type of tumor.

Fibromatosis Colli: A case report.

Radiol Case Rep 2022 Mar 28;17(3):693-695. Epub 2021 Dec 28.

Department of Radiology, Mohammed VI University Hospital, Faculty of Medicine, University Mohammed First, Oujda, Morocco.

Fibromatosis Colli also known as congenital torticollis is a rare cause of benign cervical pseudotumor in neonates, consisting of benign fibrous tissue proliferation within the sternocleidomastoid muscle, resulting in a fusiform enlargement. The cause of fibrosis is unknown; however it could be linked to trauma during pregnancy or at the time of birth, resulting in hemorrhage and, subsequently, fibrosis. Ultrasound plays a necessary role in confirming this diagnosis and follow-up. We Report a case of Fibromatosis colli in a four-week old newborn who was diagnosed using ultrasonography and treated with physiotherapy.

Diaphragmatic hernia a rare cause of acute pancreatitis: Case report.

Radiol Case Rep 2022 Mar 17;17(3):572-576. Epub 2021 Dec 17.

Department of Radiology, Mohammed VI University Hospital, Faculty of Medicine, University Mohammed First, Oujda, Morocco.

Many complications are known to occur in association with a diaphragmatic hernia. Acute pancreatitis occurring in this situation is very rare. In this paper, we report a case and describe the radiographic features of this complication. We report an unusual case of acute pancreatitis complicating a neglected post-traumatic diaphragmatic hernia in a 30-year-old male. This patient had a history of an abdominal trauma 5 years ago, and arrived at the emergency room with epigastria and left chest pain and vomiting. Serum lipase was elevated. Acute pancreatitis could be considered as an exceptional complication of diaphragmatic hernia. It is a serious diagnostic and therapeutic challenge. The fundamental roles of CT are to determine the diaphragmatic defect, the abdominal content involving, the Balthazar scoring of pancreatitis, and the presence of local complications. Even if a conservative approach is preferred when facing a diagnosis of pancreatitis, timing of surgery should be carefully considered.

Department of Radiology, Mohammed VI University Hospital, Faculty of Medicine and pharmacy, University Mohammed First, Oujda, Morocco.

The granular cell tumor or Abrikossoff's tumor is a rare tumor, most often benign in evolution. Malignant forms are exceptional. We report, here, a very rare case of granular cell tumor, localized in the perianal region, in a 54-year-old woman with lung metastases. CT and MRI with contrast showed a locally advanced tumor process in the right para-anal region associated with multiple "balloon release" lung lesions. The diagnosis was confirmed by immunostaining after surgical biopsy. Very few cases of malignant granular cell tumors with lung metastasis have been reported in the literature.

Endoluminal Leiomyoma of the Gastric Antrum: a Report of a Rare Case.

J Gastrointest Cancer 2021 Nov 29. Epub 2021 Nov 29.

Department of General Surgery, Mohammed VI University Hospital, Oujda, Morocco.

Endoluminal gastric leiomyoma (GL) of the antrum is a rare benign tumor. In this paper, we report a case of a 72-year-old patient that presented for a 1-month episode of epigastric pain. Imaging found a well-limited tumor in the antrum with extrinsic compression on ulcerated congestive mucosa. A surgical resection based on Finsterer's antrectomy with end-to-side trans-mesocolic gastro-jejunal anastomosis was performed. The histopathological examination in combination with immunohistochemistry diagnosed GL and found a diffuse and marked staining of smooth muscle actin (SMA) and h-caldesmon (h-CD) and negative expression of CD117 and DOG1. The patient was discharged without post-surgical complications and is still alive at the time of this case report writing.

Radiology, Mohammed VI University Hospital, Oujda, MAR.

Choroidal metastasis is the most common malignant intraocular tumor. Its diagnosis in a patient with known lung cancer is usually easy. However, without any context of already known cancer, further elements are needed to guide the diagnosis. We report the case of a 47-year-old patient with a history of smoking who presented a choroidal metastasis of left lower pulmonary lobe adenocarcinoma discovered on imaging. Imaging techniques, mainly ultrasonography, CT scan, and MRI can help guide the diagnosis of choroidal metastasis even in the absence of a known origin initially.

Department of Radiology, Mohammed VI University Hospital, Faculty of Medicine, University Mohammed First, BP 4806 Oujda University 60049, Morocco.

Leiomyosarcomas of the sigmoid colon are aggressive and extremely rare tumors representing less than 0.1% of all colorectal malignancies. Few cases have been reported in the literature and their imaging features need to be more detailed. We report the case of a 70 year old male patient, smoker, with a history of arterial hypertension, admitted for abdominal pain and hypogastric mass. Computed tomography has shown a voluminous heterogeneously enhancing tumor process with a necrotic center, attached to the sigmoid wall, with multiple secondary peritoneal and hepatic masses. The anatomopathological examination of the biopsy sample with immunohistochemistry allowed the diagnosis of leiomyosarcoma of the sigmoid colon. Clinical presentation and radiological features of leiomyosarcomas are non-specific, and the definitive diagnosis is only established after an anatomopathological examination.

Cardiac hydatid cyst: 2 case reports.

Radiol Case Rep 2021 Dec 10;16(12):3829-3833. Epub 2021 Oct 10.

Department of Radiology, Mohammed VI University Hospital, Faculty of Medicine, University Mohammed First, BP 4806 Oujda Universite, Oujda 60049, Morocco.

Hydatidosis is a parasitic disease that is still prevalent in regions that rear farm animals, notably along the Mediterranean coast. The liver and lungs are most commonly involved. Cardiac hydatidosis has been reported infrequently even in countries in which hydatid disease is endemic. This entity must be known because when undiagnosed and untreated, the risk of fatal complications increases. We report 2 cases of cardiac echinococcal cysts in young men. The first case is an incidentaloma in a patient admitted for pancreatitis. The second case is about a patient admitted for dyspnea. CT scan and MRI were performed showing intraventrucular cystic mass with a calcified wall which was very suggestive of a hydatid cyst diagnosis. We would like to emphasize the relevance of imaging in this context and shade some light on imaging diagnostic tools.

Failure to Thrive Revealing a Pilomyxoid Astrocytoma: An Uncommon Case Report with Literature Review.

Case Rep Pediatr 2021 27;2021:6670585. Epub 2021 Sep 27.

Department of Endocrinology, Mohammed VI Hospital, Medical School, Mohamed First University, Oujda, Morocco.

Pilomyxoid astrocytoma (PMA) is a freshly described figure of low-grade neoplasms encountered in early childhood. Nevertheless, its precise classification by the World Health Organization (WHO) is still debatable. Making an exact diagnosis relies on histological and immunohistochemical pathognomonic features with specific radiological findings. PMA behaves aggressively with a shorter progression-free survival, and its management is unfortunately still arguable. We describe a rare case of PMA involving the suprasellar region who displays symptoms consistent with diencephalic syndrome. The diagnosis was made by magnetic resonance imaging (MRI) focused on the hypothalamic-pituitary axis, and the patient underwent a subtotal tumor resection combined with chemotherapy. Diagnosis of brain tumors should be kept in mind in young children with generalized and severe unexplained loss of subcutaneous fat with failure to thrive after ruling out classical causes.

Pulmonary sarcomatoïd carcinomas are a heterogeneous group of poorly differentiated non-small cell tumors with a sarcomatous component. On imaging, they appear as peripheral or central masses, sometimes excavated. We report two cases of pulmonary sarcomatoïd lung carcinoma. The first case involves a 73-year-old active smoker who presented with dyspnea. A computed tomography (CT) scan showed a large locally advanced left lower lobar tumor process. A CT-guided biopsy was performed and the histopathological examination concluded a pulmonary sarcomatoïd carcinoma. The second case involves a 52-year-old chronic smoker who presented with hemoptysis. CT pulmonary angiography showed an excavated right upper lobar tumor. Histologic work-up of the right upper lobectomy piece objectified a pulmonary sarcomatoïd carcinoma. Pulmonary sarcomatoïd carcinoma has a nonspecific appearance on imaging and should be a part of imaging differential diagnoses in front of a large, lobulated, highly invasive lung tumor with or without excavation.

Pancreatic schwannoma- CT and MRI findings: A rare case report and review of literature.

Ann Med Surg (Lond) 2021 Aug 5;68:102664. Epub 2021 Aug 5.

Radiology Department, Mohammed VI University Hospital, Faculty of Medicine and Pharmacy, University Mohammed I, Oujda, Morocco.

Introduction: Pancreatic schwannoma (PS) is an extremely rare benign tumor. Here we describe the Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) results of PS in a 59 years old woman, as well as a review of the literature.

Case Presentation: A 59-year-old woman consulted for atypical epigastralgia without fatigue, weight loss or fever. CT scan and MRI showed a 35 mm inhomogeneous lesion with well-defined margins located in the pancreas head. The diagnosis of pancreatic tumor was made. The pathologic examination of the biopsied mass yielded a diagnosis of pancreatic schwannoma.

Clinical Discussion: On CT scans, almost all benign PS are well-defined cystic or low-density masses. MRI is helpful in characterizing their typical encapsulation.

Conclusion: The detection of pancreatic schwannoma is extremely rare. Although multiple imaging modalities are currently available, it is challenging to make an accurate diagnosis before operation.
