Omental infarction: An unusual cause of right iliac fossa pa
Introduction
Omental infarction is an uncommon mimicker of the acute appendicitis that demands emergent diagnosis to avoid the surgical management. Approximately, 85% of the cases are reported in the adults, and only a smaller proportion of 15% in the pediatrics’ patients.[1,2] The radiology plays a vital role in the accurate diagnosis of the disease. We describe a pediatric patient presenting as the right iliac fossa pain in the pediatric emergency with a clinical diagnosis of acute appendicitis and was subsequently accurately diagnosed on ultrasound and computed tomography (CT) as omental infarction and was successfully managed conservatively.

Case:
A 4-year-old male child presented to the pediatric emergency with persistent acute colicky pain in the right iliac fossa of 2 days duration. Vital signs were normal with a heart rate of 82 beats/min and blood pressure of 116/68. On examination, there was rebound tenderness and guarding in the right iliac fossa. The patient was afebrile and blood investigations including white blood cell count were unremarkable. He was referred for an ultrasound examination with a strong clinical diagnosis of acute appendicitis. Abdominal ultrasound revealed a well-defined triangular area of hyperechogenicity in the omental fat at the site of maximum tenderness, adjacent to the ascending colon. ...
