Epiploic appendagitis

Epiploic appendagitis is a medical condition that occurs when one of the fatty epiploic appendages, which arise from the serosal surface of the colon, becomes twisted (torsion) and experiences a lack of blood flow (ischemia). This condition is characterized by symptoms such as abdominal pain, which may be accompanied by constipation or diarrhea in some cases.From: Get Through Final FRCR Part A: SBAs for the Modular Examination [2019], Get Through [2017], Mayo Clinic Gastrointestinal Imaging Review [2019]

The imaging characteristics are typical for epiploic appendagitis. This usually affects women more than men and is more common in patients with a raised body mass index. Differentials would include appendicitis and diverticulitis; however the patient is young and diverticulitis would be less likely. The imaging appearances are not characteristic for appendicitis.

Acute epiploic appendagitis, is one of the infrequently seen causes of acute abdominal pain. It is more commonly found on the left abdomen, in association with left colonic diverticulae. Uncommonly, it may occur on the right lower abdomen giving a clinical picture of acute right lower abdominal pain and tenderness, which may simulate acute appendicitis, as we detected in five patients (0.5%) of our retrieved cases. They had been presented with symptoms similar to acute appendicitis, including the right iliac fossa rebound tenderness, but with no significant leukocytosis. These are multiple peritoneal pouches exiting from the serosal surface of the colon, with a vascular stalk. These pouches are mainly composed of fatty tissues and blood vessels, having a length of 0.5–5 cm. Normally, they are not seen unless there is considerable surrounding ascetic fluid. Once inflamed, they could be typically seen at CT examinations; as an oval lesion 1.5–3.5 cm in diameter, with fatty attenuation and hyperdense central spot of a thrombosed vein. [13,14] Figure 2
