Omental infarction and epiploic appendagitis are subtypes of a broader entity of abdominal fat necrosis known as intraperitoneal focal fat infarction (IFFI). IFFI is an uncommon cause of acute abdominal pain in children, and a known mimicker of acute appendicitis. The CT appearance of IFFI is well described, but the appearance is less familiar on MRI and is a potential imaging pitfall. Familiarity with the MRI appearance of IFFI is particularly timely, given the growing use of MRI in the evaluation of right lower quadrant pain in children. The purpose of this educational exhibit is to review the clinical history, pathologic appearance and treatment of IFFI, and describe MRI features that will allow the radiologist to make the correct diagnosis.

Intraperitoneal focal fat infarction is an umbrella term used to describe numerous pathologies with the two most common encountered in clinical practice being epiploic appendagitis and omental infarction. The clinical presentation often mimics an acute abdomen, which can lead to inappropriate management of the patient. While there is ample literature regarding the imaging appearance of focal fat infarction in adults, little exists regarding the imaging findings in children. The purpose of this exhibit is to demonstrate the imaging features which will allow radiologists to confidently diagnose focal fat infarction and differentiate it from more emergent causes of an acute abdomen. We will also discuss the prognosis and appropriate management, usually conservative, which is a significant difference from other causes of an acute abdomen. Read More
