Functional Bladder Paraganglioma as an Incidental Finding During Infertility Workup.

Cureus 2021 Oct 16;13(10):e18815. Epub 2021 Oct 16.

Bladder paragangliomas (PGLs) are extremely rare catecholamine-producing neuroendocrine tumors. They arise more frequently in the trigone and have unpredictable depth and behavior. Most cases typically present with a well-defined set of symptoms triggered by micturition or bladder overdistension. Besides long-term follow-up, they are usually managed by either transurethral resection (TUR) or partial cystectomy (PC). However, about 25% of all documented cases do not manifest clinically, raising both diagnosis and management challenges. This report describes an unusual case of a misdiagnosed, functional PGL arising on the bladder dome, which was fortuitously detected in a 21-year-old female during a fertility workup. Owing to its hypervascular nature and submucosal location, bladder PGL was suspected on ultrasound and CT findings and successfully diagnosed before surgery through biochemical confirmation. It was managed by cystoscopy-guided laparoscopic partial cystectomy (LPC) with good oncological and urinary outcomes, as well as no compromise of her fertility potential. To our best knowledge, this is the first case to be incidentally detected on transvaginal ultrasound during evaluation for infertility. This case also stresses the importance of considering PGL in the differential diagnosis of atypical bladder tumors, as well as conservative management through simultaneous laparoscopy and cystoscopy, when approaching young patients with large functional PGL.

Left renal vein compression complicating intragastric balloon insertion.

Radiol Case Rep 2021 Nov 20;16(11):3589-3592. Epub 2021 Sep 20.

Department of Gatroenterology, Avicenne Military Hospital, Marrakech, Morocco.

Obesity is a real public health problem and is of growing concern. People are resorting to surgical or endoscopic means to fight against overweight and obesity. In recent years, there has been a marked increase in the use of these means and in particular the insertion of a gastric balloon which seems to present less risk than surgical methods. Renal complications from intragastric balloon placement are extremely rare. We report here the case of compression of the left renal vein revealed by lumbar pain and hematuria in an overweight 39-year-old woman who benefited from the balloon gastric placement one month before symptoms. The scanner made the diagnosis and showed a good evolution after the withdrawal of the balloon.

Unilateral blindness following superior laryngeal nerve block for awake tracheal intubation in a case of posterior cervical spine surgery.

Surg Neurol Int 2020 5;11:277. Epub 2020 Sep 5.

Department of Neurosurgery, Avicenne Military Hospital of Marrakech, Mohammed V University, Rabat, Morocco.

Background: Superior laryngeal nerve block (SUPLANEB) is a popular airway anesthesia technique utilized for successful awake endotracheal intubation in patients with significant cervical spine instability. If not performed by an expert, it carries the risk of general/neurologic complications that are typically minimal/transient. However, permanent blindness and/or upper cranial nerve neuropathies may occur. Here, we describe a case in which a young patient underwent an atlantoaxial fusion for a C2 nonunion (e.g., following a fracture) complicated by unilateral blindness due to a SUPLANEB.

Case Description: A 25-year-old neurologically intact male underwent a C1-C2 posterior arthrodesis to address a nonunion of a C2 fracture. To perform the awake nasotracheal intubation, a SUPLANEB was performed using a video laryngoscope. Although the operation was uneventful, postoperatively, the patient reported left visual loss accompanied by left-sided facial numbness and hearing loss. On examination of the left eye, the anterior segment and fundus examinations were normal, but the OCT (optical coherence tomography) and retinal angiography demonstrated left-sided postischemic retinal edema with permeability of the intraocular vessels. Although the cranio-orbital computed tomography scan showed only mild pneumocephalus, the CT angiogram scan revealed abnormal air in the left carotid sheath accompanied by diffuse subcutaneous emphysema. Further, brain and orbital magnetic resonance imaging scans were normal. The patient was treated with pure oxygen, systemic steroid therapy, and nimodipine. The pneumocephalus and subcutaneous emphysema resolved on day 3. At 2 months follow-up, the patient remained blind on the left side, but had no further neurological deficits.

Conclusion: Blindness and upper cranial nerves neuropathies should be considered as potential complications of SUPLANEB. Notably, these deficits were not directly related to the operative positioning or neurosurgical spinal procedure.

A Rare Case of Malignant Tumor of the Larynx with Good Prognosis: Laryngeal Chondrosarcoma.

Case Rep Oncol Med 2019 5;2019:9468194. Epub 2019 May 5.

Department of Otolaryngology, Avicenne Military Hospital, Marrakech, Morocco.

Laryngeal chondrosarcoma is a rare laryngeal tumor that most frequently originates from the cricoid cartilage. The majority of lesions are low grade and the distinction from benign chondromas must be made. We present a case of a laryngeal chondrosarcoma arising from the cricoid cartilage in a 75-year-old Arab man who presented with hoarseness, dysphonia, and dyspnea. Endoscopic and radiological examinations showed a mass of the wall of his larynx with displaced structures, airway obstruction, and destruction of the cartilage. The patient underwent total laryngectomy. Histological examination supported the diagnosis of low-grade chondrosarcoma. Five months later, the radiological and clinical findings showed no evidence of recurrence or metastases. Laryngeal chondrosarcomas remain a rare disease of unknown etiology, with slow and insidious symptoms. The treatment is surgical, given the importance of preserving the larynx to patients' quality of life. The prognosis is favorable and metastases rarely occur.

Lipoma with Agenesis of Corpus Callosum: 2 Case Reports and Literature Review.

World Neurosurg 2019 05 28;125:123-125. Epub 2019 Jan 28.

Department of Radiology, Avicenne Military Hospital, Marrakech, Morocco.

Background: Intracranial lipomas are extremely rare fat-containing lesions, comprising 0.1-0.5% of all primary brain tumors. Lipoma of corpus callosum, the commonest variety of all intracranial lipomas (40%-50%), is associated with varying degrees of dysgenesis of corpus callosum and generally remains asymptomatic.

Case Description: In this study, we report 2 cases of pericallosal lipomas admitted with seizures and discuss the clinical and radiologic findings in light of the literature.

Conclusions: Lipomas of the corpus callosum are rare, fat-containing asymptomatic lesions, mostly associated with dysgenesis of the corpus callosum. Diagnosis accidentally occurs during diagnostic procedures in case of an encephalic disorder. Magnetic resonance imaging is the most useful modality for a differential diagnosis. Prognosis and symptoms depend on associated malformations. Surgical treatment is mostly not indicated and should be avoided.
