目的探讨血管母细胞瘤的MR I特征性表现,提高其正确诊断率。方法回顾性分析17例血管母细胞瘤的MR I资料,分析肿瘤的特点。结果12例肿瘤表现为囊腔结节型(70.6%),MR I表现为囊性病灶和附壁瘤结节,增强后瘤结节明显强化;5例为实质型肿瘤(29.4%),表现为实质性肿块,其内或周围可见流空血管,增强后肿瘤明显强化。结论血管母细胞瘤具有特征性的MR I表现,特别是增强扫描是评价血管母细胞瘤的最佳检查手段。
Objective To investigate the characteristic features of MR I in hemangioblastoma and to improve its correct diagnosis rate. Methods Retrospective analysis of MR I data of 17 cases of hemangioblastoma and analysis of the characteristics of the tumor. Results The tumors showed cystic nodules (70.6%) in 12 cases. MR I showed cystic lesions and adherent nodules. The enhanced nodules were obviously enhanced in 5 of 12 cases (29.4%) As a substantial mass, it can be seen inside or around the empty flow of blood vessels, enhanced significantly enhanced after the tumor. Conclusions Hemangioblastoma has the characteristic MR I manifestations, especially enhanced scan is the best examination of hemangioblastoma.
