摘要 目的探讨分析脊髓血管母细胞瘤的MRI特征,提高认知能力。方法回顾性分析经临床病理证实的15例脊髓血管母细胞瘤的MRI表现,全部病例均进行MRI平扫及增强扫描。结果所有病灶均位于髓内,15例中单发13例,多发2例,其中,呈“大囊小结节”的特征性表现的14例,囊性部分均为T1WI低信号,T2WI高信号,结节部分均呈T1WI等或略低信号,T2WI略高或高信号,强化后可见明显结节强化影,结节型的1例,信号T1wI等或略低信号,T2WI略高或高信号,11例内可见血管流空,14例脊髓内均可见空洞,13例中强化结节均很小且与脊髓增粗囊变的范围明显不成比例。结论MRI中的特征性影像学表现如强化结节、血管流空及结节和脊髓水肿不成比例等对于脊髓血管母细胞瘤的定位及定性诊断有重要意义。
