CT in Malignant Pleural Mesothelioma
電腦斷層攝影對惡性肋膜間皮瘤的評估
摘要
11位患有惡性肋膜間皮瘤(malignant pleural mesothelioma)的病人接受了CT檢查，發現典型的腫瘤在CT上呈現小葉狀助膜腫塊圍繞著肺部且合併不等量的助膜積水。對病灶範圍，附近器官侵襲或病灶的延伸，CT提供了良好的診斷資料及對此腫瘤作進一步的治療方針。CT雖不能提供對腫瘤的正確診斷，一旦發現腫瘤邊緣與胸腔壁形成鈍角(obtuse angle)並附有鈣化斑塊時也可暗示為助膜間皮瘤。因為此腫瘤常保有一層完整被膜，對於與腫瘤緊貼的附近器官是否已被腫瘤侵入及能否完全手術切除必需由胸腔探查術來做最後的診斷。

The pre-treatment CT scans of 11 cases of malignant pleural mesothelioma were reviewed to assess the value of computed tomography in the diagnostic work up of this tumor. In our study CT typically showed a lobulated rind of pleural mass encasing the lung and associated with variable amount of pleural effusion. The configuration of the tumor, local extension to the mediastinum, pericardium, diaphragm, and contralateral thorax were well depicted on CT. Though CT cannot provided a specific diagnosis, a tumor with a tapered periphery associated with calcified pleural plaques is suggestive of mesothelioma. As mesothelioma is usually well encapsulated, tumor abutting on adjacent mediastinal structures as seen in CT should not be regarded as a feature of tumor invasion and the resectability of the tumor should not rely solely on CT. CT is not a good imaging modality in determining transdiaphragmatic spread of this tumor.
