摘要
目的:探讨血管母细胞瘤MR表现及MR的诊断价值。方法:对22例经手术病理证实的血管母细胞瘤MR表现进行回顾分析。结果:病灶位于小脑半球14例,小脑蚓部4例,颈髓2例,延髓1例,小脑合并颈髓病灶1例。囊腔结节型14例,囊肿型2例,实质型6例。增强扫描肿瘤结节及实质型瘤体均明显强化。6例MR表现有血管流空影。瘤周轻或中度水肿。结论:MR对血管母细胞瘤的诊断及鉴别诊断有重要价值。
Objective： To further raise the knowledge of MR manifestation of hemangioblastomas. Methods： The MR appearance of 22 cases of hemangioblastomas proved by surgery and pathology were analyzed retrospectively. Results： The location of hemangioblastomas 14 cases was in hemisphere cerebellum, 4 cases in vennis cerebelli, 2 cases in cervical cord, 1 case in medulla oblungata, 1 case in hemisphere cerebellum and cervical cord, 14 cases with cyst and tubercle type, 2 cases with cyst type, 6 cases with sohd type. The tumor tubercle and tumor body of solid type were highly enhanced. Blood flow void phenomena could be seen in 6 cases with MR. There was slight and medium edema around the tumor. Conclusion：MR supplemented show important for diagnosis and differential diagnosis of hemangioblastemas.
