目的探讨MR I对囊性毛细胞型星形细胞瘤的诊断价值。方法回顾性分析26例经手术病理证实的囊性毛细胞型星形细胞瘤MR I表现,研究肿瘤的部位、形态和信号特征。结果肿瘤位于大脑半球6例,小脑20例,依据MR I表现,可分为单纯囊性、囊性伴壁结节。结论囊性毛细胞型星形细胞好发于年轻人,最常见于小脑,有较典型MR I表现,因此根据MR I表现结合临床资料,可望做出定性诊断。
Objective To investigate the diagnostic value of MR Ⅰ in cystic hairy cell astrocytoma. Methods The MR I manifestations of cystic dendritic astrocytoma confirmed by pathology were retrospectively analyzed. The location, morphology and signal characteristics of the tumor were studied. Results The tumors were located in the hemisphere of the brain in 6 cases and in the cerebellum in 20 cases. According to MR findings, the tumors could be divided into simple cystic and cystic wall nodules. Conclusion Cystic trichoderma astrocytoma occurs predominantly in young people, most commonly in the cerebellum. It shows typical MRI features. Therefore, based on MR findings and clinical data, it is expected to make a qualitative diagnosis.
