We report a case of solitary ectopic thymoma at the ligamentum arteriosum, which was resected with thoracoscopic surgery. A 62-year-old male patient received chemoradiation therapy for laryngeal cancer approximately 1 year before. The present computed tomography scan indicated a mass (diameter, 2 cm) at the ligamentum arteriosum. Furthermore, positron emission tomography showed an abnormal accumulation on the mass. Malignant lymphoma and laryngeal cancer with lymph node metastasis were suspected, and thoracoscopic surgery was performed. The tumor had a clear margin;therefore, it could be extirpated easily. The results of the postoperative pathological examination indicated that the tumor was an ectopic thymoma. The patient was discharged 3 days after the surgery because he showed good clinical course and was kept under careful observation.
我们报告一例位于动脉韧带处的孤立性异位胸腺瘤，该肿瘤通过胸腔镜手术切除。一名62岁男性患者约1年前因喉癌接受了放化疗。目前的计算机断层扫描显示动脉韧带处有一个肿块（直径2 cm）。此外，正电子发射断层扫描显示该肿块有异常聚集。怀疑为恶性淋巴瘤和伴有淋巴结转移的喉癌，遂进行了胸腔镜手术。肿瘤边界清晰，因此易于切除。术后病理检查结果表明该肿瘤为异位胸腺瘤。患者术后3天出院，因其临床过程良好，并持续接受密切观察。
