颅内脉络膜裂囊肿的低场强MRI诊断
Low-Field MRI in Diagnosis of Choroiodal Fissure Cyst in Brain
-
摘要: 目的探讨脑部脉络膜裂囊肿的低场强核磁共振(MRI)表现及其诊断价值.方法回顾分析13例脑部脉络膜裂囊肿的低场强MRI表现,并分析其与临床的关系.结果 13例均位于脉络膜裂内,其中1例发生于双侧,7例发生于右侧,5例发生于左侧,表现为圆形、椭圆形或梭形及边界光滑锐利的脑脊液信号,囊壁及其内外均无异常信号.结论低场强MRI诊断脉络膜裂囊肿具有特异性.MRI具有多平面成像的特点,可清楚地显示脉络膜裂,有利于与脑内其他囊性病变鉴别.Abstract: Objective To investigate the performance and value of low-field MRI in diagnosis of choroidal fissure cyst in brain.Method We retrospectively analyzed the low-field MRI findings of 13 choroidal fissure cyst in brain,and analyzed their correlation with clinical findings.Results 13 cases were cracked in the choroid,1 case occurred in the bilateral,7 cases occurred in the right side,5 cases occurred in the left side,the performance of the round,oval or spindle and smooth sharp boundary of the cerebrospinal flu...
