A 47-year-old male who previously underwent emergency surgery for type A aortic dissection presented to the emergency department 4 years later with acute chest pain radiating to his back and a significant drop in hemoglobin. Clinical presentation was concerning for aortic graft failure, but imaging revealed a large (6.0 × 3.2 × 12.8 cm) soft tissue mediastinal mass that was not present 4 years before. Pathologic analysis revealed a rare thymic cyst with a hemorrhagic component. This was a challenging case from diagnostic and operative perspectives, involving the expertise of both cardiac and thoracic surgical teams.
一名47岁男性，曾因A型主动脉夹层接受急诊手术，4年后因急性胸痛放射至背部且血红蛋白显著下降就诊于急诊科。临床表现提示主动脉移植物功能衰竭，但影像学检查发现一个巨大的（6.0×3.2×12.8cm）纵隔软组织肿块，而4年前并不存在。病理分析显示为一个罕见的伴有出血成分的胸腺囊肿。从诊断和手术角度来看，这是一个具有挑战性的病例，需要心脏外科和胸外科团队的专业知识。
