目的分析颅内血管母细胞瘤的MRI影像特征，提高对该病认识。方法回顾性分析16例经手术病理证实的颅内血管母细胞瘤，均行常规MRI平扫、DWI及Gd-DTPA增强扫描。结果肿瘤全部位于幕下，其中位于小脑半球者14例，占87.5%；小脑蚓部者2例，占12.5%。囊结节型13例（81.25%），壁结节邻近软脑膜侧并显著强化；实质型3例(18.75%)，均呈不均匀的显著强化，其中1例可见囊变区。结论血管母细胞瘤MRI表现具有一定的特征性，术前MRI检查有重要的临床价值。

Objective To summarize the MR imaging findings of intracranial hemangioblastomas, and to improve the comprehension of it. Methods MR imaging findings were retrospective analyzed in 16 cases of hemangioblastomas. MR plain scan and enhancement scan were performed in all these cases. Results All lesions were showed in posterior fossa:14 lesions located in cerebellar hemisphere, and 2 lesions in cerebellar vermis. 13 lesions were showed as macrocystic form with markedly enhanced nodule, 3 lesions were showed as markedly enhanced solid form of which with micro cyst in 1 lesion. Conclusion MR imaging findings of hemangioblastomas were characteristic, most of hemangioblastomas can be preoperatively diagnosed by MR imaging.
