摘　　要：目的:分析腹膜假性黏液瘤(PMP)的CT表现,以提高对该病的诊断水平。方法:回顾性分析27例经病理证实的腹膜假性黏液瘤的病例资料,其中25例行全腹部CT平扫和双期增强检查;2例行全腹部CT平扫,根据黏液样腹水容积的不同,分组分析PMP的CT影像特征。结果:27例PMP均出现不同程度的低密度黏液样腹水,左、右膈下间隙黏液样腹水容积无明显差异。22例出现肝、脾边缘的扇贝样压迹,23例出现腹膜或网膜污垢样改变,17例出现小肠向中心或一侧移位,5例出现钙化,16例出现纤维分隔。结论:CT检查可以较早发现PMP并显示其浸润范围,PMP黏液样腹水量较大时不容易发现原发病灶,需结合多种影像学表现及临床症状进行综合诊断。Objective：To analyze the CT features of pseudomyxoma peritonei（PMP） ,in order to improve the diagnosis accuracy of the disease. Methods： 27 cases with pathology proved pseudomyxoma peritonei （PMP） were analyzed retrospec- tively. Of these, 25 cases underwent plain and dual-phase enhanced CT scanning of the abdomen, 2 cases had plain scan only. The CT features were divided into two groups according to the volume of mucinous ascites,and were analyzed respectively. Results：Of the 27 cases with PMP,various volume of low attenuated mucinous ascites were shown. No obvious difference was revealed in the volume of ascites within left or right infra-diaphramatic spaces. Peri-hepatic and peri-sptenic scallop-like indentation was detected in 22 cases,peritoneal or omental smudged thickening was observed in 23 cases, 17 cases had uni- lateral or concentric small bowel displacement. Calcification were shown in 5 cases and fibrous septae were found in 16 ca ses. Conclusion：CT scanning is very valuable in the early diagnosis of pseudomyxoma peritonei, the extent could be revealed. Yet the primary disease might not be assessed in patients with large amount of mucinous ascites,comprehensive clinical and imaging studies are necessary for the diagnosis.
