Intraneural hemangiomas are rare benign neoplasms. We report the case of a 53‑year‑old female with a hemangioma in a spinal nerve root. The patient presented with muscular atropy of the right arm wihout obvious predisposing factors one year ago. MRI demonstrated a heterogeneously enhanced lesion adjacent to the right C4/5 intervertebral foramen. The lesion was considered to be a schwannoma preoperatively. Histologically, the lesion was abundant with intervening malformed vascular mass lined by simple squamous epithelial cells, and CD31 was positively stained at these epithelial cells by immunohistochemistry. The patient underwent microsurgical resection and recovered without complications.
神经内血管瘤是罕见的良性肿瘤。我们报告一例53岁女性，其脊神经根存在血管瘤。该患者于一年前无明显诱因出现右臂肌肉萎缩。磁共振成像（MRI）显示右侧C4/5椎间孔附近有一个不均匀强化的病变。术前该病变被认为是神经鞘瘤。组织学检查显示，病变中有大量夹杂着由单层鳞状上皮细胞衬里的畸形血管团，免疫组织化学检查显示这些上皮细胞中CD31呈阳性染色。该患者接受了显微手术切除，术后恢复良好，无并发症。
