Hemangioma is a rare tumor of the mediastinum. We report a case of cavernous hemangioma of the anterior mediastinum that was incidentally detected by chest radiography during a routine health check. A mass lesion was seen in the anterior mediastinum on computed tomography and magnetic resonance imaging of the chest. Because a thymoma with cystic degeneration was suspected preoperatively, extended thymectomy was performed. The tumor was confined to the left lobe of the thymus without invasion into the adjacent structures. It measured 42x32x17 mm, and was completely resected without any major bleeding. Pathological examination led to the diagnosis of cavernous hemangioma. A total of 61 cases of mediastinal hemangioma, including our case, reported in Japan over the past 50 years are reviewed.
血管瘤是一种罕见的纵隔肿瘤。我们报告一例前纵隔海绵状血管瘤，该病例在常规健康检查时通过胸部X线摄影偶然发现。胸部计算机断层扫描和磁共振成像显示前纵隔有一肿块病变。由于术前怀疑是囊性变的胸腺瘤，故行扩大胸腺切除术。肿瘤局限于胸腺左叶，未侵犯相邻结构。肿瘤大小为42×32×17mm，完整切除，无大出血。病理检查确诊为海绵状血管瘤。本文回顾了过去50年日本报道的包括我们这例在内的61例纵隔血管瘤病例。
