| 目的 探讨椎管内髓外硬膜下毛细血管瘤的临床及MRI特征。方法 回顾性分析5例经手术病理确诊的椎管内髓外硬膜下毛细血管瘤的临床资料及MRI表现。结果 临床表现:胸背痛伴双下肢麻木、无力4例,颈部疼痛伴双上肢疼痛1例。MRI示肿块均为单发,均位于椎管内硬脊膜下脊髓背侧,胸段4例,颈段1例;T1WI呈等(4例)或低信号(1例),T2WI呈高信号,增强后多均匀强化(4例);病灶周围可见含铁血黄素沉积(1例)、脊膜尾征(1例)及肿块头侧可见引流血管(1例)。结论 椎管内髓外硬膜下毛细血管瘤好发于中年人,位于脊髓背侧。MRI特征表现为肿块周围引流血管、含铁血黄素沉积、脊膜尾征、显著均匀强化。 |

| Objective To explore the clinical and MRI features of spinal intradural extramedullary capillary hemangioma. Methods The clinical data and MRI findings of five patients with spinal intradural extramedullary capillary hemangioma proved by surgical pathology were retrospectively analyzed. Results Four patients presented with upper back pain/numbness and weakness in lower extremities, and one with pain in posterior neck and upper extremities. On MR imaging, a total of five single intradural extramedullary capillary hemangiomas were found posterior to the spinal cord, four of which were at the thoracic level and one at the cervical level. The lesions showed iso- or hypointensity on T1WI and hyperintensity on T2WI. After constrast administration, four cases showed typical strong homogeneous enhancement. Dural tail sign (n=1), draining vessels (n=1) and rim of hemosiderin (n=1) were found in these tumors. Conclusion Intradural extramedullary hemangioma typically occurs in the posterior aspect of the spinal cord in middle-aged adults. On MR imaging, it is characterized by draining vessels, rim of hemosiderin, dural tail sign and strong homogeneous enhancement after contrast administration. |
