| 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。

| Abstract: | 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 showed the solid type.In 20 cases of tumors,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. |
