摘　　要：目的探讨颅内实性血管母细胞瘤的MRI特征及病理特点。方法回顾分析10例经手术和病理证实的实性血管母细胞瘤的影像资料,对其MRI特点进行探讨。结果肿瘤位于小脑半球8例,眼眶内1例,第四脑室内1例,影像表现为边界清楚的实性软组织肿块;病变T1WI呈等、稍低信号混杂,T2WI呈等、高信号混杂,占位效应明显而水肿轻;肿瘤内部信号欠均匀;瘤内及瘤周见多发异常血管影,增强扫描实性肿瘤均非常显著强化。结论实性血管母细胞瘤发病率很低,但其MR表现具有一定的特征性,MRI检查有利于肿瘤术前定位及定性诊断。Objective The MRI features and pathological features of the solid intracranial hemangioblastoma are discussed.Methods The MRI data of 10 cases of solid hemangioblastoma confirmed by operation and pathology were analyzed retrospectively.Results There were 8 tumors located in the infratentorial cerebellum, 1 case in the fourth ventricle and 1 case in orbital.MRI showed a soft tissue masses with clear boundary;equal or slightly low signal on T1 WI, equal or slightly high signal on T2 WI;the space-occupying effect was obvious with slight edema;multiple abnormal vessels were observed in tumor and peritumor;MRI enhancement scanning showed the solid tumors were significantly enhanced.Conclusion The incidence of the solid hemangioblastoma is very low, but MR performance is of characteristic.MRI examination facilitates the tumor positioning and qualitative diagnosis.
