摘　　要：目的　探讨恶性局限性腹膜间皮瘤的CT诊断价值。方法　分析 4例恶性局限性腹膜间皮瘤的CT表现特点及其病理基础。结果　 4例恶性局限性腹膜间皮瘤的CT表现均为巨大孤立性肿块 ,瘤径平均大小为 13cm。其中 3例为囊实性 ,以多囊性为主 ;1例为实性 ,内见不规则坏死。增强扫描 ,4例肿瘤实质区均显著强化 ,密度增高最大者达 10 6HU ,平均 76HU。无远处转移及腹水。结论　恶性局限性腹膜间皮瘤CT表现具有多囊变。Objective To study the value of CT diagnosis in localized malignant peritoneal mesothelioma. Methods CT features of 4 cases with localized malignant peritoneal mesothelioma and the pathological basis were analyzed. Results All 4 cases showed a large localized mass with an average size of 13 cm. 3 of 4 cases were cystic solid predominantly multi cystic; another case was solid accompanied by necrosis. Contrast CT demonstrated marked enhancement in the solid portion of tumor in all 4 cases, the highest CT density was 106 HU(average 76 HU). There was no distant metastasis and ascites. Conclusion Multi cysts, remarkable enhancement of the solid area and no distant metastasis may be the main characteristic CT features of localized malignant peritoneal mesothelioma.
