Capillary hemangiomas are common soft tissue tumors on the skin or mucosa of the head and neck in the early childhood, but very rare in the neuraxis. A 47-year-old man presented with one month history of back pain on the lower thoracic area, radiating pain to both legs, and hypesthesia below T7 dermatome. Thoracic spine MRI showed 1×1.3×1.5 cm, well-defined intradural mass at T6-7 disc space level, which showed isointensity to spinal cord on T1, heterogeneous isointensity on T2-weighted images, and homogeneous strong enhancement. The patient underwent T6-7 total laminotomy, complete tumor removal and laminoplasty. Histologically, the mass showed a capsulated nodular lesion composed of capillary-sized vascular channels, which were tightly packed into nodules separated by fibrous septa. These features were consistent with capillary hemangioma.
毛细血管瘤是儿童早期头颈部皮肤或黏膜常见的软组织肿瘤，但在神经轴极为罕见。一名47岁男性，有下胸部区域背痛1个月病史，疼痛放射至双腿，T7皮节以下感觉减退。胸椎MRI显示在T6 - 7椎间盘水平有一个1×1.3×1.5 cm、边界清晰的硬膜内肿块，T1加权像上与脊髓等信号，T2加权像上呈不均匀等信号，且均匀强化明显。患者接受了T6 - 7全椎板切开术、肿瘤全切及椎板成形术。组织学上，肿块为有包膜的结节性病变，由毛细血管大小的血管通道组成，这些血管紧密排列成结节，由纤维间隔分隔。这些特征符合毛细血管瘤。
