Introduction Omental infarction is a rare occurrence in the paediatric population. It often presents as an acute abdomen that can mimic acute appendicitis and cholecystitis.
Methods Six cases of omental infarction in children, proven on histopathology, were retrospectively reviewed for their clinical presentation and imaging findings on ultrasonography and computed tomography.
Results These cases revealed clinical and imaging findings on computed tomography that were suggestive and helpful in the pre-operative diagnosis of omental infarction. Findings on ultrasonography were less specific. Histopathological specimens revealed findings of vasculitis in all cases.
Conclusion There are clinical and imaging features that will help in the pre-operative diagnosis of this uncommon condition. We also postulate vasculitis as a possible underlying pathology for omental infarction.
