摘要
目的:探讨血管母细胞瘤的MRI诊断。方法:回顾性分析经手术病理证实的24例血管母细胞瘤,探讨其MRI表现。结果:23例血管母细胞瘤位于后颅窝,1例位于右顶枕叶。16例表现为大囊小结节型,结节强化明显;8例表现为实质型;20例瘤内或瘤周可见血管流空信号。本组MRI正确诊断22例,准确率为91.7%。结论:MRI是诊断血管母细胞瘤的有效检查方法,但不典型者需与胶质瘤、单纯囊肿、脑膜瘤、动静脉畸形等鉴别。
Objective： To evaluate the MRI diagnosis of hemangioblastoma. Methods： 24 cases of hemangioblastomas proved by surgery and pathology were retrospectively analyzed, and its MRI findings were discussed. Results： 23 cases of hemangioblastomas located in the posterior cranial fossa. 16 hemangioblastomas demonstrated the type of big cyst with a nodule and the nodules were obviously enhanced, 8 lesions shewed the solid type. In 20 eases of tuners, the blood vessel flow-void-signal was seen intra-or peri-lesion. Conclusion： MRI is an effective method in diagnosis of hemangioblastoma, however, the atypical tumors should be differentiated from glioma, simple cyst, meningioma and AVM.
