时间:2009-11-22  来源:uhrad.com  作者:十月十日编译 【复制分享】【讨论-纠错】【举报

Clinical Presentation: A 37 y/o female with acute onset of lower abdominal pain 37岁  女性  以急性下腹痛为主Cz1影像园XCTMR.com

Imaging Findings(影像所见):Computed tomographic (CT) images enhanced with intravenous contrast show an oval lesion with fat attenuation, measuring approximately 2 cm in the left side of the colon. This lesion has surrounding inflammatory changes with contrast enhancement.静脉对比剂增强CT表现:左侧结肠旁见一大小约为2cm卵圆形病变,邻近脂肪受压变薄。病变周围呈炎性改变,增强后强化。Cz1影像园XCTMR.com

Diagnosis(诊断):Acute epiploic appendagitis 急性肠脂垂炎Cz1影像园XCTMR.com

Discussion(讨论):Cz1影像园XCTMR.com
Acute epiploic appendagitis most commonly manifests with acute lower quadrant pain. Its clinical features are similar to thoseof acute diverticulitis or, less commonly, acute appendicitis. The conditions that may mimic acute epiploic appendagitis at computed tomography (CT) include acute omental infarction, mesenteric panniculitis, fat-containing tumor, and primary and secondary acute inflammatory processes in the large bowel (eg, diverticulitis and appendicitis). Whereas the location of acute epiploic appendagitis is most commonly adjacent to the sigmoid colon, acute omental infarction is typically located in the right lower quadrant and often is mistaken for acute appendicitis. It is important to correctly diagnose acute epiploic appendagitis and acute omental infarction on CT images because these conditions may be mistaken for acute abdomen, and the mistake may lead to unnecessary surgery. The CT features of acute epiploic appendagitis include an oval lesion 1.5Cz1影像园XCTMR.com
