Abstract： 目的探讨海洛因烟雾吸入所致的海绵状脑病的CT、MRI征象,提高对该病的认识和诊断水平.方法对4例加热吸食海洛因烟雾的患者进行颅脑CT或MR平扫和增强,MRI常规行SE序列平扫、增强,以及液体衰减反转恢复序列(FLAIR)、磁共振波谱(MRS)检查.结果 2例CT扫描的病例表现为双侧小脑半球、脑干、内囊后肢、大脑脚、胼胝体压部、大脑后部脑白质对称性低密度灶,无强化.2例MRI检查的病例也表现为相应区域长T1、长T2信号,无强化.FLAIR像呈高信号,小脑病变较大脑明显,顶枕叶病变较额叶显著,MRS显示脑白质变性,乳酸升高.结论该病的CT及MRI表现较具特征性,结合病史,可作出诊断.
