摘　　要：目的认识和提高腹膜假性黏液瘤的CT表现及诊断。方法回顾性分析16例经病理或细胞学检查证实的腹膜假性黏液瘤的CT和临床表现。结果腹膜假性黏液瘤是以黏液性腹水为特征,临床主要表现为腹胀、腹块等。依据CT表现不同可分为弥漫性和局限性两种类型,主要CT表现包括腹水内密度不均匀8例,肝脾表面黏液样结节10例,多发分隔的囊性病变5例和网膜增厚或“网膜饼”征6例。结论典型的CT表现可以诊断腹膜假性黏液瘤,CT检查可为临床治疗的选择和改善预后提供有价值的信息。Objective.. To recognize CT findings of pseudomyxoma peritonei and to promote the identified diagnosis of the disease. Methods：CT images and clinical data were retrospectively reviewed in 16 eases with pseudomyxoma peritonei proven by histopathology or cytology. Results： Pseudomyxoma peritonei was characterized by low density mutinous ascites on CT. It was divided into two types, diffuse and focal, by CT features. The main CT findings were as follow：heterogeneous ascites （n= 8）, scalloping of the liver and spleen margins （n~ 10）, multiple septal cystic lesions （n= $） and omental thickening or omental cake （n = 6）. Conclusion： The classical CT findings can suggest the diagnosis of pseudomyxoma perltonei. CT scan may give helpful information in selecting therapy and improving the prognosis of this disease.
