前言目的探讨脑血吸虫病的MRI表现及特征,提高对本病定性诊断水平。方法回顾性分析我院诊治的12例经临床和/或手术病理证实的脑血吸虫病患者的MRI资料。结果所有病例均行MRI平扫及增强扫描。12例中11例病灶位于大脑半球,1例位于小脑。MRI平扫时11例病变区内可见多发结节影,呈等或稍长T1,稍长或等T2信号,1例病变区内有斑片状出血,T1及T2像均为高信号;1例为单发大结节,呈长T1及长T2信号,结节周边均有大片状呈长T1及长T2信号的水肿带。MRI增强扫描后11例病灶呈多发的结节状强化,部分小结节互相融合成较大结节,1例单发大结节增强后呈不均匀环状强化,强化程度在注射Gd-DTPA后40s、6min及12min时无明显差异;有8例病变区域内有斑点状、斑片状及泥沙样强化。结论脑血吸虫的MRI征象具有一定的特征性,结合临床资料和实验室检查,可以对本病作出准确的诊断。
