目的：探讨假膜性肠炎（PMC）的CT表现及其诊断价值。方法：回顾性分析经临床粪便微生物检测确诊为PMC且CT检查阳性（结肠壁厚度＞4mm）的23例患者的CT资料，对其CT表现进行总结。结果：23例PMC患者中，病变最易累及左半结肠。病变肠壁厚度4～25 mm，平均15 mm；肠道弥漫性受累10例，节段性受累13例；肠管扩张21例，其中2例出现“手风琴征”，2例未见肠管扩张，形成“鱼骨征”；13例出现结肠皱襞结节状增厚，19例出现“晕征”，16例出现腹水。结论：单纯依靠CT诊断P MC比较困难，但是了解P MC的相关影像学表现对缩小鉴别诊断的范围有帮助。

Objective:To investigate CT manifestations of pseudomembranous colitis (PMC)and to improve the un-derstanding of this disease.Methods:On CT,those with colonic wall thickness greater than 4mm were considered positive (CT-positive patients).23 cases positive CT materials and proven by stool microbiological detection were retrospectively an-alyzed.Results:These patients had segmental involvement (13 cases)or diffuse involvement (10 cases),with the left colon most often affected (16 cases).Wall thickening (4~25mm,mean:15mm)was present in all the CT-positive cases.Bowel distention was seen in 21 cases,2 cases without bowel distention exhibited"fish-bone sign".Nodular fold thickening of co-lonic folds was seen in 13 cases,"halo sign"in 19 cases,and ascites in 16 cases.Conclusion:Though it was difficult to diag-nose PMC only with CT modality,understanding all kinds of imaging findings of PMC would help radiologists to narrow the scope of differential diagnosis.
