【摘要】：目的:探讨颅内节细胞胶质瘤的磁共振成像特点。方法:回顾性分析我院经手术病理证实的节细胞胶质瘤15例,年龄3~69岁,平均29.3岁,分析其影像表现,并与病理对照。结果:本组病例病理分型WHOⅠ级1例,Ⅰ~Ⅱ级13例,Ⅲ级1例;MRI表现为:幕上病灶13例,幕下病灶2例。33.3%(5/15)为囊实性占位,60%(9/15)为实性占位,6.7%(1/15)为囊性占位;平扫时T1WI中实性成分呈稍高或等信号,T2WI中呈高信号;瘤周水肿多轻度;多数为明显强化,少数低级别病灶呈线样轻度强化;MRS多提示NAA稍降低,Cho明显升高,Cho/Cr明显升高,Cho/NAA明显升高。结论:30岁以下患者,幕上实性/囊实性病灶,轻度水肿,病灶明显强化者,诊断及鉴别诊断时应考虑节细胞胶质瘤。
