We report the computed tomography (CT) findings of an arterio-esophageal communication from an aberrant right subclavian artery aneurysm which had eroded into the esophagus. Pathologic correlation is provided. To our knowledge, this is the first CT demonstration of an aberrant right subclavian aneurysm causing a communication to the esophagus reported in the literature. Previously, one CT case of a left aberrant subclavian artery aneurysm that had ruptured into the esophagus, had been described. The characteristic location of the aberrant vessel with aneurysmal dilation and the presence of abnormal air identified within the wall of the aneurysm on CT, helped establish the diagnosis antemortem.
我们报告了一例由异常右锁骨下动脉瘤侵蚀食管导致的动脉-食管瘘的计算机断层扫描（CT）表现，并提供了病理对照。据我们所知，这是文献中首次报道的由异常右锁骨下动脉瘤导致与食管相通的CT表现。此前，曾有一例左异常锁骨下动脉瘤破裂入食管的CT病例报道。异常血管的特征性位置、动脉瘤样扩张以及CT上动脉瘤壁内出现的异常气体，有助于生前诊断。
