The retrotracheal triangle is an area in the posterior superior mediastinum where abnormal structures may be detected in as many as 2% of chest radiographs. The authors describe the anatomy of this space and the abnormalities found therein, including vascular abnormalities (aberrant right subclavian artery, right aortic arch, double aortic arch, true and false aortic aneurysms), thoracic duct lesions, esophageal abnormalities (benign and malignant tumors, congenital atresia, duplication cysts, foreign bodies, diverticula, and achalasia), and miscellaneous entities (intrathoracic thyroid, bronchogenic cyst, bronchogenic carcinoma, cystic hygroma, and emphysema). Careful attention to this long-neglected area on chest radiographs can yield findings of abnormalities not otherwise suspected.
气管后三角是后上纵隔的一个区域，在多达2%的胸部X线片中可能检测到异常结构。作者描述了该区域的解剖结构以及在其中发现的异常情况，包括血管异常（迷走右锁骨下动脉、右主动脉弓、双主动脉弓、真性和假性主动脉瘤）、胸导管病变、食管异常（良性和恶性肿瘤、先天性闭锁、重复囊肿、异物、憩室和贲门失弛缓症）以及其他各种情况（胸内甲状腺、支气管囊肿、支气管癌、囊性水瘤和气肿）。在胸部X线片上仔细关注这个长期被忽视的区域，可以发现原本未被怀疑的异常情况。
