Typical causes of intermittent esophageal dysphagia in a young person include eosinophilic esophagitis, esophageal dysmotility and esophageal rings. We report a 35-year-old male with a one year history of intermittent dysphagia to solid foods. After the endoscopic removal of a food bolus, a barium swallow revealed extrinsic compression of the proximal esophagus. Computed tomography angiogram revealed an aberrant right subclavian artery (ARSA) coursing behind the esophagus, suggesting the diagnosis of dysphagia lusoria. Although rare, dysphagia lusoria represents an important consideration in the differential diagnosis of intermittent esophageal dysphagia in a young adult.
年轻人间歇性食管吞咽困难的典型病因包括嗜酸性粒细胞性食管炎、食管动力障碍和食管环。我们报告一名35岁男性，有一年固体食物间歇性吞咽困难病史。在内镜下取出食物团块后，吞钡检查显示食管近端有外压性改变。计算机断层血管造影显示一条异常的右锁骨下动脉（ARSA）走行于食管后方，提示为食管性吞咽困难的诊断。尽管罕见，但食管性吞咽困难仍是年轻成人间歇性食管吞咽困难鉴别诊断中的一个重要考虑因素。
