摘　　要：目的:探讨腹膜假性粘液瘤的影像表现及对本病的诊断价值。方法:回顾性分析25例经手术及病理证实病例的影像表现。结果:腹膜假性粘液瘤有以下影像表现:①腹腔弥漫积液(25/25),肝、脾边缘病灶CT值明显高于腹盆腔病灶;②肝、脾边缘"扇贝样"压迹(25/25);③腹、盆腔散在点状、不规则索条状钙化灶(18/25);④可肝(2/25)、脾(10/25)转移,脾脏转移多见;⑤腹膜后不受累及(25/25);⑥磁共振T2WI显示病灶内有多发不规则分隔(2/2)。结论:PMP的影像学检查应以CT检查为首选,结合MR表现,应能大部分准确术前诊断,对累及范围也能准确评估,在PMP患者的复发和病情评估中也有重要价值。Objective：To investigate the imaging features and value of imaging modality for the diagnosis of pseudomyxoma peritoneum（PMP）.Methods：The imaging appearances of 25 patients with histologically proved PMP were retrospectively reviewed and analyzed.Results：PMP had such typical imaging findings as diffuse ascites and scalloping margin on the edge of liver and spleen,in which CT value was higher than other lesions lying in abdomen and pelvis.There were multiple metastasis in liver and spleen,especially in spleen;multiple spotted and irregular calcification were found in abdomen and pelvis;invasions and metastasis were not found in retroperitonium;the were multiple irregular septa in the lesions on T2WI.Conclusion：CT is the preferred imaging for the diagnosis of PMP;Combined with MR imaging appearances,most PMP can be correctly diagnosed,and the lesion＇s extent and the patient＇s conditions can also be evaluated,which also helps to find out the recurrence of PMP.
