摘　　要：目的 探讨恶性腹膜间皮瘤（MPM）的MSCT特征性表现。方法 回顾性分析本院26例经病理证实的MPM患者的病例资料，分析CT征象，并与临床病理进行对照研究。结果 局限性腹膜间皮瘤（LMPM）5例，均表现为孤立性包块，病变位于腹腔3例，盆腔1例，腹膜后1例，CT示4例呈囊实性，1例实性，增强扫描实性成分多呈轻中度强化。弥漫性腹膜间皮瘤（DMPM） 21例，CT表现为腹膜不规则增厚、腹膜多发结节，其中7例网膜“饼状”改变，5例腹膜“盔甲样”增厚，增厚的腹膜及结节多呈明显强化。26例中出现局部浸润7例，肝转移和腹膜后淋巴结肿大各1例。结论 MSCT在MPM的诊断中具有重要地位，能发现和显示病变、确定病变范围，同时为选择治疗及判断预后提供重要参考。Objective To discuss different features of malignant peritoneal mesothelioma （MPM） in MSCT scan and the related pathological basis. Methods 26 patients with MPM comfirmed pathologically underwent MSCT scan. The dates were analyzed retro- spectively,and the features of MSCT scan and the related pathological basis were further compared. Results 5 cases of localized MPM （LMPM） presented with isolated masses. 3 cases located in abdominal cavity, 1 in pelvic cavity and 1 in retroperitoneal space. 4 of 5 cases were cystic-solid mass,and another 1 case was solid mass. Contrast CT demonstrated mildly or moderate enhancement in the solid portion of tumor. Twenty-one cases of diffuse MPM presented with peritoneum irregularly thickening or multiple lesions. The imaging findings include caking （7） and armature thickening of peritoneum （5）. Contrast CT demonstrated obvious enhancement in the thickening of peritoneum and multiple lesions. 7 cases invaded adjacent organs. Retroperitoneal lymphatic metastasis was observed in 1 case and liver metastasis was recorded in 1 case. Conclusion MSCT provided useful information regarding detection,displaying and identifying the scope of MPM. The features are helpful to increase the diagnostic accuracy and could provide important information for therapy and prognosis.
