腹膜间皮瘤的CT表现

CT Manifestations of Peritoneal Mesothelioma

作者总结１６例腹膜间皮瘤ＣＴ表现，并与大体病理检查进行对照研究。主要ＣＴ表现包括：腹水（１６／１６，１００％），腹膜不规则增厚粘连（１３／１６，８１％）和腹膜结节（５／１６，３１％），大网膜（１０／１６，６３％）和肠系膜受累（１１／１６，６９％），盆腔肿块（９／１６，５６％），胸膜受累（７／１６，４４％）。早期腹膜病变ＣＴ检查不易发现；当腹膜、大网膜和肠系膜广泛增厚粘连时，ＣＴ所见可提示此病的诊断；但不易与卵巢癌等肿瘤转移鉴别。确诊主要依靠病理学。

This article reported the results of CT study of 16 patients with histologically proven peritoneal mesothelioma. The CT findings included : ascites (16/16, 100% );irregular thick-ening of peritoneum with adhesion (13/16, 81%);peritoneal nodules(5/16, 31% );pelvic mass (9/16, 56% ); mesenteric involvement (11/16, 69% ); omental involvement (10/16, 63% ) and pleural involvement ( 7/16, 44% ). It is difficult for CT to demonstrate early peritoneal pathological changes. On the basis of diffuse involvement of peritoneum, omentum and mesentery, CT may sug-gest the diagnosis of peritoneal mesothelioma. However, it is difficut to differentiate this condition from carcinomatosis, particularly from an primary ovarian origin, Histological confirmation is always necessary.
