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.
描述原发性网膜附件炎和网膜节段性梗死的超声及CT表现。
1986年至1996年期间，我院有13例患者出现这些病理表现（6例大网膜梗死，7例网膜附件炎）。对超声（n = 13）和CT表现（n = 7）进行回顾性分析。
超声显示中等回声、卵圆形病变，附着于腹膜。CT扫描显示肿块为脂肪区域，密度略有增加，有时周边有高密度环。必须排除由相邻器官炎症引起的继发性网膜或阑尾受累。
网膜节段性梗死和原发性网膜附件炎具有特征性的超声及CT表现，有助于正确诊断。
