低度恶性腹膜囊性间皮瘤的影像与病理

THE IMAGING AND PATHOLOGICAL ASPECTS OF LOW-GRADE MALIGNANT PERITONEAL CYSTIC MESOTHELIOMA

探讨低度恶性腹膜囊性间皮瘤的影像学表现与病理基础 ,回顾性分析经病理证实的 14例低度恶性腹膜囊性间皮瘤的X线、CT或MRI影像表现特点。本组 14例腹膜低度恶性囊性间皮瘤以中年女性多见 ,男女之比为 3∶11。主要症状为腹部疼痛或不适 ,10例CT或MRI检查发现 3例为局限性单发囊性肿块 ,5例为多发囊性结节 ,6例为弥漫性囊性结节。大多数低度恶性腹膜囊性间皮瘤的X线、CT或MRI显示有一定的特征性改变 。

To evaluating the imaging features and the pathological basis of low grade malignant cystic mesothelioma of the peritoneum (LGMCMP). In 14 cases of LGMCMP, radiographic imaging (X ray, CT, and MRI) was reviewed, and diagnosis was established by pathology. The majority of the patients were middle aged women. The main symptoms were abdominal pain or discomfort. CT and MRI revealed solitary cystic masses in 3 of them, multiple cystic nodules in 5, and diffuse cystic nodules in 6. It is therefore concluded that X ray, CT, and MRI are helpful in revealing the characteristics of LGMCMP and confirm the diagnosis.
