目的 探讨小脑实性血管母细胞瘤的影像表现特点。方法 搜集 7例经病理证实的小脑实性血管母细胞瘤的MRI资 料，详细分析其MRI表现。结果 5例肿瘤位于小脑半球，2例位于小脑蚓部。5例CT检查,4例平扫肿块表现为混杂 等、低密度，1例呈均匀稍高密度。3例边界不清，周围可见水肿区；2例边界较清，周围可见少许水肿或不明显水 肿；增强扫描均表现为显著强化。7例 MRI检查，表现为T1WI呈等、稍低信号或混杂信号，T2WI及FLAIR上呈高信 号，5例肿块内部或周围可见血管流空影，增强后肿瘤呈显著强化；DWI上均呈低信号；2例 MRS可见低Cho和NAA 峰，明显增高的Lip峰。结论 CT与MRI对小脑实性血管母细胞瘤的诊断具有重要价值。

Objective To probe into imaging performance characteristics of the cerebellum solid hemangioblastoma. Methods MRI manifestations of the seven cases cerebellum solid hemangioblastoma proved by pathology were analysed in detailed. Results 5 cases located in cerebellar hemisphere, 2 cases located in the cerebellar vermis. 5 cases CT scan, of 4 cases plain scan mass were mixed and/or low density, 1 case was slightly high density homogeneously. 3 cases were obscure boundary and edema around area. 2 case were boundary clearly and around a few edema or not obvious edema. Enhanced scan all performance was significantly improved. 7 cases MR scan, slightly low signal or mixed signals on T1WI, high signal on T2WI and FLAIR, vascular flow empty mass inside or around visible in 5 cases, all the tumor was significantly enhancement and low signal on DWI. 2 cases were low Cho and NAA peak as well significantly higher Lip peak. Conclusion CT and MRI have an important value in diagnosis of the cerebellum solid hemangioblastoma.
