Abstract

To describe US and CT findings of primary epiploic appendicitis and segmental infarction of the omentum.From 1986 through 1996 thirteen patients presented with these pathological findings at our institution (6 patients with greater omental infarction and 7 patients with epiploic appendicitis). US (n = 13) and CT findings (n = 7) were retrospectively reviewed.US revealed moderately hyperechoic, ovoid lesions adherent to the peritoneum. On CT scans the masses appeared as areas of fat with slightly increased attenuation and sometimes with hyperattenuating peripheral rims. Secondary omental or appendiceal involvement caused by inflammation of adjacent organs has to be excluded.Segmental infarction of the omentum and primary epiploic appendicitis have characteristic US and CT features that enable the correct diagnosis.
