Computed tomographic appearances of 147 surgically proven mediastinal tumors (113 benign and 34 malignant lesions) were evaluated paying special attention to their localization or extension. Ten of the 113 benign lesions (9%) showed atypical or unique localization or extension, and were divided into three groups. In the first group, two lymphangiomas and one bronchogenic cyst spread over both the precardiovascular and the retrocardiovascular compartments, mimicking a malignant lesion. In the second group, the single cases of thymic hypertrophy, thymic cyst, schwannoma, and pericardial cyst were located atypically in the retrocardiovascular compartment. In the last group, two esophageal leiomyomas and one esophageal duplication showed upward and downward longitudinal extension beyond the azygos arch and the aortic arch.
对147例经手术证实的纵隔肿瘤（113例良性病变和34例恶性病变）的计算机断层扫描表现进行了评估，特别关注其定位或扩展情况。113例良性病变中有10例（9%）表现出非典型或独特的定位或扩展，并分为三组。在第一组中，2例淋巴管瘤和1例支气管囊肿蔓延至心血管前和心血管后间隙，类似恶性病变。在第二组中，胸腺肥大、胸腺囊肿、神经鞘瘤和心包囊肿的单发病例非典型地位于心血管后间隙。在最后一组中，2例食管平滑肌瘤和1例食管重复畸形表现为向上和向下纵向延伸超过奇静脉弓和主动脉弓。
