椎管内毛细血管瘤MRI与病理对照研究

MRI Study of Intraspinal Capillary Hemangioma

目的:提高对椎管内毛细血管瘤的诊断水平。方法:对经MR检查及手术病理证实的椎管内毛细血管瘤5例进行总结及分析,分析MRI特征并与病理结果对照。结果:5例椎管内毛细血管瘤,位于脊髓内2例,髓外硬膜下3例,呈等信号或稍长T1、长T2信号。增强扫描5例均显著强化,瘤体境界清晰,3例均匀强化,2例强化欠均匀,病灶内可见点状及条状不强化区,为血栓或纤维间隔。3例可见引流血管纵向走行与病灶相连。结论:MRI对椎管内毛细血管瘤有较高的诊断价值。

Objective：To study the MRI features and pathologic findings of intraspinal capillary hemangloma comparatively in order to improve the diagnosis of this disease. Methods： 5 cases of intraspinal capillary hemangioma with MR imaging and the succedent surgical pathology were analyzed and summarized. Results： 2 cases of them were located within the spinal cord and 3 cases in the spinal intradural extramedullary. The lesions showed iso- or hypointensity on T1WI and hyperintensity on T2WI. After enhancement,the tumors obviously enhanced and clearly delineated from the surrounding tissue. 3 out of 5 showed enhanced drainage vessels. Conclusion： MRI plays an important role in the diagnosis of intraspinal capillary hemangioma.
