We present two cases demonstrating, on CT examination, heavily calcified mass lesions associated with malignant pleural mesothelioma in workers occupationally exposed to asbestos. These masses proved to be osteogenic sarcomatous degeneration within mesotheliomas. The observation of dense calcification within a pleural mass should raise a suspicion of osteosarcomatous degeneration if it is seen in conjunction with other classic signs of malignant pleural mesothelioma.
我们报告两例病例，在CT检查中显示职业性接触石棉的工人患有与恶性胸膜间皮瘤相关的重度钙化肿块病变。这些肿块被证实为间皮瘤内的骨肉瘤变性。如果在胸膜肿块内观察到致密钙化，同时伴有恶性胸膜间皮瘤的其他典型征象，则应怀疑骨肉瘤变性。
