Accurate diagnosis of infarction of omentum and appendices epiploicae by computed tomography.

Segmental infarction of the omentum and epiploic appendages presents with acute abdominal findings that may be confused with a surgical illness. Computed tomography, however, demonstrates a consistent and well-recognized pattern that allows safe, nonoperative treatment. Infarction of omental or mesenteric fat may present clinically as localized peritonitis, mimicking appendicitis, diverticulitis, or cholecystitis.
