Inflammation of an epiploic appendage (appendix epiploicae [NA6]), which is a rare cause of focal abdominal pain in otherwise healthy patients; it may be asymptomatic or clinically mimic diverticulitis or appendicitis.
Further imaging with an intravenous contrast enhanced CT scan of the abdomen showed a hyperdense rim lesion anteriorly, adjacent to the sigmoid colon in the left lower quadrant, along with inflammatory stranding that was consistent with epiploic appendagitis (EA) (Figure 1B).
Epiploic appendagitis mimics acute abdomen or is a condition associated with acute abdomen, although it is usually not treated by emergent surgical intervention and has characteristic findings on computed tomography (1).
CT scans are routinely performed nowadays both to diagnose acute appendicitis and to identify mimics such as right ureteric calculus, epiploic appendagitis, torsion of a Meckel's diverticulum, mesenteric adenitis, inflammatory bowel disease, colitis, gynaecological disorders, and right-sided diverticulitis .
The clinical differential diagnosis of acute abdominal pain depends on age and localization of the pain and includes acute pancreatitis, acute appendicitis, cholecystitis, gastroduodenal ulcer, diverticulitis, epiploic appendagitis, and other intra-abdominal inflammatory conditions.
