Abstract

The computed tomography manifestations of 39 patients with histologically proved anterior mediastinal tumors were studied by categorizing the tumors by content as solid homogeneous, cystic homogeneous, and heterogeneous. Among 24 solid tumors, thymomas were easily distinguished by their lack of invasiveness from malignant lymphomas and germ-cell tumors. Among 11 cystic tumors, pericardial and thymic cysts were differentiated from cystic teratomas and bronchogenic cysts by their lack of recognizable capsules with or without calcification. The differential diagnosis of a variety of tumors of the anterior mediastinum was facilitated by computed tomography in all but a few exceptional cases.

摘要

对39例经组织学证实的前纵隔肿瘤患者的计算机断层扫描表现进行了研究，根据肿瘤内容物将其分为实性均匀、囊性均匀和不均匀三类。在24例实性肿瘤中，胸腺瘤因其无侵袭性而易于与恶性淋巴瘤和生殖细胞肿瘤区分开来。在11例囊性肿瘤中，心包囊肿和胸腺囊肿因其有无钙化而缺乏可识别的包膜，从而与囊性畸胎瘤和支气管源性囊肿区分开来。除少数例外情况外，计算机断层扫描有助于对各种前纵隔肿瘤进行鉴别诊断。
