Abstract

A 49-year-old woman presented with cough, and chest X-rays showed an abnormal shadow. Chest computed tomography showed an anterior mediastinal 40-mm mass with massive calcification. The patient underwent mediastinal tumor excision performed using video-assisted thoracoscopic surgery. Pathological findings revealed the tumor to be a type B3 thymoma, with massive calcification occupying almost all of the thymoma. Due to high risk of recurrence, we performed completion thymectomy. Pathological findings revealed no remaining thymoma tissue in the residual thymus. Mediastinal tumor with entire calcification could be a candidate for surgical excision.

摘要

一名49岁女性因咳嗽就诊，胸部X线显示有异常阴影。胸部计算机断层扫描显示前纵隔有一个40毫米的肿块，伴有大量钙化。患者接受了电视辅助胸腔镜手术切除纵隔肿瘤。病理结果显示该肿瘤为B3型胸腺瘤，大量钙化几乎占据了整个胸腺瘤。由于复发风险高，我们进行了完整胸腺切除术。病理结果显示残留胸腺中无剩余胸腺瘤组织。伴有完全钙化的纵隔肿瘤可作为手术切除的候选对象。
