摘要
目的探讨脑部脉络膜裂囊肿的MRI表现特点。方法回顾性分析25例脉络膜裂囊肿病人的MRI资料。所有病例均行MR平扫,2例同时行MR增强扫描,5例行CT平扫检查。结果25例均表现为脉络膜裂内类圆形或纺锤形脑脊液信号灶,边界清,周围无水肿。2例增强扫描者均无强化。结论MRI是诊断脉络膜裂囊肿并与其他病变鉴别的重要依据,对于指导临床有重要意义。
Objective To investigate the MRI characteristics of ehoroid fissure cysts of the brain. Methods Twentyfive patients with choroid fissure cysts diagnosed by MR imaging were reviewed. Enhancement scanning was done in two of them at the same time, and CT was performed in five cases. Results The cysts were situated within the choroidal fissure in all cases, representing as round or spindle lesions with clear border, homogenous consistency, signal intensity identical to CSF on all sequences, without associated edema. There was no abnormal enhancement in two patients studied after injection of Gd-DTPA. Conclusion MRI is important in diagnosing choroid fissure cysts and differentiating from other diseases.
