A 44-year-old male without history of infection, catheterization, or instrumentation of his left upper extremity presented with a slow-growing pulsatile mass of his forearm. Ultrasound and magnetic resonance imaging revealed a large radial artery aneurysm. Because of worsening paresthesia and pain in his hand, the patient underwent surgical excision of the aneurysm. Pathology revealed an extremely rare case of completely intravascular myopericytoma, originating from the radial artery wall and causing large aneurysmal dilation. Postoperatively, the patient had no vascular or sensorimotor deficits. We suggest that arterial wall myopericytoma can be managed with surgical excision for tissue diagnosis and symptomatic relief.
一名44岁男性，无左上肢体感染、插管或器械操作史，出现前臂缓慢生长的搏动性肿块。超声和磁共振成像显示为巨大的桡动脉动脉瘤。由于手部感觉异常和疼痛加重，患者接受了动脉瘤手术切除。病理显示为极罕见的完全血管内肌周细胞瘤，起源于桡动脉壁并导致巨大动脉瘤样扩张。术后，患者无血管或感觉运动功能障碍。我们建议，动脉壁肌周细胞瘤可通过手术切除进行组织诊断并缓解症状。
