摘要
目的回顾性分析原发性腹膜癌(primary peritoneal carcinoma,PPC)的CT、MRI表现,提高对PPC的诊断与鉴别诊断水平。资料与方法7例确诊PPC患者中4例行常规全腹部CT平扫+增强扫描,3例行下腹部MRI平扫+增强扫描,分析腹膜与卵巢病变以及腹腔积液情况。结果 (1)PPC的腹膜病变形态表现有:"污垢"状腹膜改变、"饼"状腹膜改变、腹膜线样增厚、腹膜肿块与结节及腹腔积液。(2)6例卵巢体积无增大,1例卵巢轻度增大。结论腹部CT、MRI增强扫描可以显示腹膜病变并筛查腹膜外脏器病变,有助于PPC的临床诊断。
Objective To evaluate the CT and MRI features of primary peritoneal carcinoma, in order to improve the diagnosis and differential diagnosis. Materials and Methods Seven patients with primary peritoneal carcinoma were collected in the study. Four patients underwent CT plain and contrast scan, another 3 patients underwent MR scan with T1- weighted, fat-suppressed T2-weighted and contrast-enhanced fat-suppressed T1-weighted sequence. The pathological findings of peritoneum, ovary, ascites were observed. Results （ 1 ） The imaging findings of peritoneum included omental caking, finely infiltrated fat with a ＂smudged＂ appearance, sheetlike thickening of the peritoneum, peritoneal nodules and mass, large amount of ascites. （2） One patient showed slightly enlarged ovary. Conclusion Contrast-enhanced CT and MRI scan can detected the pathological findings of peritoneum, which is helpful to diagnosis the primary peritoneal carcinoma.
