We report a case of an aneurysm originating from an aberrant right subclavian artery, which was incidentally found as a compression deformity of the upper esophagus on a barium study in a 46-year-old man. Computed tomography (CT) clearly demonstrated the aneurysm of the aberrant right subclavian artery. In particular, reconstructed three-dimensional CT (3D-CT) was valuable in evaluating the positional relationships between the anomalous vessel with aneurysm and other structures.
我们报告一例起源于异常右锁骨下动脉的动脉瘤病例，该病例是在一名46岁男性的钡餐检查中偶然发现的，表现为食管上段的压迫性畸形。计算机断层扫描（CT）清晰地显示了异常右锁骨下动脉的动脉瘤。特别是，重建的三维CT（3D-CT）对于评估动脉瘤异常血管与其他结构之间的位置关系很有价值。
