The authors report a new case of hemangiopericytoma in an elderly man. An asymptomatic mediastinal mass was found on a routine chest film. C.T. guided fine-needle biopsy was diagnostic. These rare lesions are clinically and radiologically aspecific and require pathologic proof. The value of percutaneous biopsy before therapeutic decision is emphasized.
作者报告了一例老年男性血管外皮细胞瘤的新病例。在常规胸部X光片上发现了一个无症状的纵隔肿块。CT引导下的细针穿刺活检具有诊断意义。这些罕见病变在临床和放射学上无特异性，需要病理证据。强调了在做出治疗决策前进行经皮活检的价值。
