Results Mediastinal pleural involvement, circumferential pleural thickening, nodularity, irregularity of pleural contour, and infiltration of the chest wall and/ or diaphragm were most suggestive of a malignant cause on CT and MR images. 结果无论在CT或MRI图象上,纵隔胸膜受累、环绕形胸膜增厚,结节状、轮郭不规则以及胸壁和/或横膈受累等征象均强烈提示恶性胸膜病变。
