腹膜粘液癌病的CT影像学表现

The Diagnostic Value of CT for Peritoneal Mucinous Carcinomatosis （PMCA）.

目的 探讨腹膜粘液癌病（PMCA）的CT影像学表现。方法 回顾性分析经手术病理证实4例PMCA，原发病灶胃腺癌1例，胆管腺癌1例，阑尾粘液腺癌1例，卵巢粘液囊腺癌1例；其中2例CT平扫，2例CT平扫＋增强扫描。结果 CT除发现原发病变外，3例CT表现盆腹腔粘液性腹水，1例B超提示上腹部有少量腹水，CT值25-32HU，内见分隔。4例均可见腹膜和／或网膜增厚，网膜饼形成，1例病灶内见钙化灶。结论 发生于盆腹腔脏器原发病灶，伴有多发囊性病灶，CT值高于水，腹膜或／和网膜结节样增厚者应考虑诊断本病。

Objective To present the computed tomographic （CT） findings of peritoneal mucinous carcinomatosis. Methods Imaging studies, 4 cases of pathological confirmed peritoneal mucinous carcinomatosis abdominal CT scans were reviewed, including I case of gastric adenocarcinoma, I case of bile duct adenocarcinoma, I case of appendiceal mucinous adenocarcinoma, and I case of ovary mucinous cystadenocarcinoma, had accepted CT examination. 2 cases had accepted plain scan. 2 cases had accepted plain scan and enhancement scan. Results Besides the primary affection, Ascites was found in all cases, CT value 25 - 32HU, with internal septation in all. The thickening of the peritonaeum and retina was found in all cases, Calcification was found in one case. Conclusion Radiologists should be familiar with the typical CT findings of synchronous mucinous tumors associated with PMCA.
