Abdominal Imaging Findings in Critically Ill Children With Multisystem Inflammatory Syndrome Associated With COVID-19.

Pediatr Infect Dis J 2021 02;40(2):e82-e83

Department of Radiology, Newark Beth Israel Medical Center, Robert Wood Johnson Barnabas Health, Rutgers New Jersey Medical School, New Jersey.

We report findings on abdominal imaging in critically ill children admitted with MIS-C. On sonography, hepatomegaly, nephromegaly, gallbladder wall edema, ascites, intestinal inflammation and mesenteric lymphadenopathy were seen, while CT showed fluid-filled small bowel loops, mural thickening of the terminal ileum, diffuse lymphadenopathy, and moderate ascites.

Paediatric abdominal pain in the time of COVID-19: a new diagnostic dilemma.

J Surg Case Rep 2020 Sep 21;2020(9):rjaa337. Epub 2020 Sep 21.

Department of Paediatric Surgery, Alder Hey in the Park, Liverpool, UK.

The diagnostic uncertainty for children with abdominal pain has increased during the COVID-19 pandemic with the additional consideration of both COVID-19 and paediatric inflammatory multisystem syndrome-temporally associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (PIMS-TS) alongside appendicitis, mesenteric adenitis and other less common causes of abdominal pain. We describe the cases of two children who presented with severe abdominal pain, non-bilious vomiting and high temperatures during the UK's first peak of the COVID-19 pandemic. Laboratory and abdominal ultrasound features were similar for both children but symptom progression in combination with cross-sectional abdominal imaging enabled differentiation between PIMS-TS and appendicitis with concurrent COVID-19.

Atypical and novel presentations of Coronavirus Disease 2019: a case series of three children.

Br J Biomed Sci 2021 Jan 15;78(1):47-52. Epub 2020 Jul 15.

Pediatric Infectious Disease Research Center, Tehran University of Medical Science , Tehran, Iran.

Typical presentations of Coronavirus Disease 2019 (Covid-19) including respiratory symptoms (cough, respiratory distress and hypoxia), fever and dyspnoea are considered main symptoms in adults, but atypical presentation in children could be a diagnostic challenge. We report three children whose initial presentation was gastrointestinal, and in whom Covid-19 infection was found, concluding that cases of acute appendicitis, mesenteric adenitis and flank tenderness may mask an infection with this virus, and should therefore be investigated.

Unilateral inguinal lymphadenitis caused by Yersinia pseudotuberculosis. A case report.

J Infect Chemother 2020 Jul 5;26(7):762-764. Epub 2020 May 5.

Department of Laboratory Medicine, Hyogo Prefectural Kakogawa Medical Center, Kakogawa, Japan.

Acute inguinal lymphadenitis is usually caused by lower extremity infection and sexually transmitted diseases, such as chancroid, lymphogranuloma venereum, genital herpes, or syphilis. Yersinia pseudotuberculosis is a non-spore forming, pleomorphic, non-lactose fermenting Gram negative bacillus and a member of the family Enterobacteriaceae, which is associated with diarrheal diseases. It also causes mesenteric lymphadenitis at the terminal ileum, which can be clinically indistinguishable from acute appendicitis (pseudoappendicitis). Read More

Rationale: Fibromatoses or desmoid tumors are relatively rare tumors derived from the musculoaponeurotic system. This tumor has no specific clinical symptoms and it is sometimes misdiagnosed as other diseases such as gastrointestinal stromal tumors (GISTs).

Patient Concerns: A 28-year-old man visited Peking Union Medical College for a tangible abdominal mass without abdominal pain or distention. Read More

Is the presence of echo-rich periportal cuffing in the liver indicator for abdominal inflammation in pediatric patients?

Med Ultrason 2019 Aug;21(3):225-231

Department of Pediatric Surgery, Hitit University Erol Olcok Training and Research Hospital, Corum, Turkey..

Aims: Hyperechoic/echo-rich periportal cuffing (ErPC) is defined as an increase in echogenicity relative to the adjacentliver parenchyma. Thickening in the periportal area may occur with proliferation of bile ducts, hemorrhage, oedema, fibrosis,inflammatory changes or a combination of these. The aim of this study is to determine which intraabdominal inflammatory diseases are associated with the presence of ErPC in the pediatric population and to calculate the sensitivity and specificity of this finding.

Mesenteric Tuberculosis Masquerading as Carcinoid Tumor on Conventional Imaging and DOTANOC Positron Emission Tomography/Computed Tomography: Uncommon Presentation of a Common Disease.

Indian J Nucl Med 2019 Jul-Sep;34(3):216-219

Department of Radio-Diagnosis, All India Institute of Medical Sciences, Ansari Nagar, New Delhi, India.

Carcinoid tumor of the mesentery has a classical imaging morphology. A specific diagnosis can often be provided on the basis of clinical history, elevated serum neuroendocrine markers, and uptake on somatostatin receptor-based radiotracer studies. Although a number of inflammatory and neoplastic conditions may mimic carcinoid tumor on many of these modalities, uptake on Ga-DOTANOC positron emission tomography/computed tomography (PET/CT) is considered specific.

Hypercalcemia as a rare presentation of angioimmunoblastic T cell lymphoma: a case report.

J Med Case Rep 2018 Apr 20;12(1):101. Epub 2018 Apr 20.

Department of Internal Medicine, Wayne State University School of Medicine, Rochester Hills, MI, USA.

Background: Angioimmunoblastic T cell lymphoma is a rare malignancy, accounting for only 2% of all non-Hodgkin lymphomas, first described in the 1970s and subsequently accepted as a distinct entity in the current World Health Organization classification. Due to the paucity of this disease, there is still no identifiable etiology, no consistent risk factors, and the pathogenesis remains unclear.

Case Presentation: An 83-year-old Caucasian man presented to an emergency department with palpitations and was found to have atrial fibrillation. Read More

Biomed Res Int 2017 2;2017:9784565. Epub 2017 Feb 2.

Pediatric Emergency Department, Foundation IRCCS Ca' Granda Ospedale Maggiore Policlinico, Milan, Italy; Pediatric Unit, Università degli Studi di Milano, Foundation IRCCS Ca' Granda Ospedale Maggiore Policlinico, Milan, Italy.

Acute nonspecific, or primary, mesenteric lymphadenitis is a self-limiting inflammatory condition affecting the mesenteric lymph nodes, whose presentation mimics appendicitis or intussusception. It typically occurs in children, adolescents, and young adults. White blood count and C-reactive protein are of limited usefulness in distinguishing between patients with and without mesenteric lymphadenitis. Read More

Clin Radiol 2015 Aug 11;70(8):881-9. Epub 2015 Jun 11.

Division of Pediatric Radiology, Department of Radiology, The Pennsylvania State University, College of Medicine, Hershey, PA, USA.

As the utilization of MRI in the assessment for paediatric appendicitis increases in clinical practice, it is important to recognize alternative diagnoses as the cause of abdominal pain. The purpose of this review is to share our institution's experience using MRI in the evaluation of 510 paediatric patients presenting with suspected appendicitis over a 30 month interval (July 2011 to December 2013). An alternative diagnosis was documented in 98/510 (19. Read More

Sonographic distinction between acute suppurative appendicitis and viral appendiceal lymphoid hyperplasia ("pink appendix") with pathological correlation.

Ultrasound Q 2015 Jun;31(2):95-8

Departments of *Radiology and †Pathology, Yale University School of Medicine, New Haven, CT.

The viral etiology of mesenteric lymphadenitis may also affect the lymphoid tissue of the appendix in children giving rise to symptomatic appendiceal lymphoid hyperplasia, the so-called "pink appendix." The present study used ultrasound (US) to determine if certain sonographic features correlated with appendiceal pathological findings. Our results indicate that a fluid-filled appendix always correlates with a suppurative or mixed pathological appearance that likely merits surgery. Read More

The role of US in finding intussusception and alternative diagnosis: a report of 100 pediatric cases.

Acta Radiol 2015 Feb 13;56(2):228-33. Epub 2014 Feb 13.

Department of Radiology, Kangwon National University College of Medicine, Kangwon-do, Republic of Korea.

Background: The clinical diagnosis of intussusception remains challenging, because many children with intussusception may present with non-specific signs and symptoms, which overlap with other conditions. Therefore imaging, in particular ultrasonography (US), plays a significant role in the management of these patients.

Purpose: To evaluate how US can contribute to the diagnosis in clinically suspected intussusception and finding alternative diagnosis. Read More
