Endemic malignant pleural mesothelioma (MPM) in Turkey is related to two mineral fibers, tremolite asbestos and fibrous zeolite (erionite). Thirteen cases of MPM from the Cappadocian area, where the soil is rich in erionite, and 29 cases of MPM, from villages whose occupants have high asbestos exposure, were examined by CT. The CT findings of the two groups of MPM were compared with respect to the configuration of the pleural lesions, stage of disease, fissural involvement, pleural effusion, presence of calcified pleural plaques, and chronic fibrosing pleuritis. In erionite-related MPM the pleural lesions were flat and smooth in 69.1%; in asbestos-related MPM the lesions were nodular in 55.1%. Stage IV disease, calcified pleural plaques, and chronic fibrosing pleuritis were more common in the erionite-related MPM. The rest of the findings were similar in both groups. The early radiological diagnosis of erionite-related MPM may be even more difficult because of the similarity of the pleural lesions to chronic fibrosing pleuritis.
土耳其的地方性恶性胸膜间皮瘤（MPM）与两种矿物纤维有关，即透闪石石棉和纤维沸石（毛沸石）。对来自卡帕多西亚地区（土壤富含毛沸石）的13例MPM患者以及来自居住者石棉暴露量高的村庄的29例MPM患者进行了CT检查。比较了两组MPM患者的CT结果，包括胸膜病变的形态、疾病分期、叶间裂受累情况、胸腔积液、胸膜钙化斑的存在以及慢性纤维性胸膜炎。在毛沸石相关的MPM中，69.1%的胸膜病变是扁平且光滑的；在石棉相关的MPM中，55.1%的病变是结节状的。IV期疾病、胸膜钙化斑和慢性纤维性胸膜炎在毛沸石相关的MPM中更为常见。两组的其他检查结果相似。由于胸膜病变与慢性纤维性胸膜炎相似，毛沸石相关MPM的早期影像学诊断可能更加困难。
