摘　　要：目的探讨脑部脉络膜裂囊肿的MR影像表现及其诊断价值。材料与方法结合文献回顾性分析28例MRI诊断为脉络膜裂囊肿患者的临床及影像学资料。结果 28例脉络裂囊肿于轴面、冠状面及矢状面MRI扫描像均可明确显示,而以冠状面显示最佳,其中24例(85.71%)位于右侧,发生率显著高于左侧(P<0.05),表现为界限清楚的囊性病变,病灶周围均无水肿,MR增强扫描无强化。结论 MR具有多参数、多平面成像的特点,可明确脉络膜裂囊肿的诊断并能够与其他囊性病变相鉴别。Objective： To investigate the magnetic resonance imaging（MRI） manifestations and diagnostic value in patients with choroidal fissure cyst in the brain. Materials and Methods： MRI appearance and clinical data of 28 patients with choroidal fissure cyst were analyzed retrospectively. Results： All of the 28 choroidal fissure cysts were shown in axial,sagittal and coronal planes explicitly,but best displayed in coronal plane 24（85.71%） of them were seen in the right hemisphere,with a signifi cant higher frequency than the left hemisphere（P〈0.05）. The cysts were situated within the choroidal fissure in all cases,and all cases were single,with clear boundary,no associated edema,and showed no enhancement in Gd-DTPA enhanced MRI scan. Conclusions： MRI has characteristics of multi-parameter,multi-sequence imaging,not only can confirm the diagnosis of choroidal fissure cyst but also can differentiate the choroidal fi ssure cyst from other cystic lesions.
