摘　　要：目的：探讨5例经病理证实的腹膜假性黏液瘤（PM P ）的C T 及M RI表现及病理组织学特征，提高对该病的诊断水平。方法回顾分析5例经腹腔穿刺或手术证实的PMP的CT、MRI资料并结合文献讨论，分析其CT、MRI表现及临床病理特点。结果5例中，1例为阑尾黏液腺癌，1例为急性阑尾炎术后2年，1例为无任何原发肿瘤，1例为十二指肠黏液腺癌，1例为双侧卵巢癌，C T、M RI表现为腹腔内分隔样囊性病变或／和腹膜弥漫性饼状“胶冻腹”改变，并1例肝、脾周围多发结节样、扇贝样压迹。结论腹部CT、MRI平扫＋增强可以显示PMP病灶部位、形态，有一定的特殊影像学表现。Objective To discuss CT and MRI performance and pathologic features about pseudomyxoma peritonei （PMP）con‐firmed by pathology which improves the PMP diagnosis level .Methods The CT and MRI informations about five cases with pseud‐omyxoma peritonei confirmed by abdominal puncture or surgery were analyzed retrospectively .Analyze the CT and MRI performance and clinical pathologic characteristics .Results In 5 cases ,one case of appendiceal mucous adenocarcinoma ,one case of acute appendi‐citis surgeried 2 years ago ,one case without any primary tumor ,one case of duodenal mucous adenocarcinoma ,one case of bilateral ovarian cancer with intra‐abdominal separated cystic lesion and/or peritoneal diffuse pie “frozen abdomen” change showed by CT , MRI ,and one case with pressure trace like scallops sample and multiple nodular around liver and spleen .Conclusion The lesion area and the shape of peritoneum pseudo myxoma can be showed by CT ,MRI scans .There is a certain special imaging feature .
