| 目的通过复习脉络裂的解剖结构,增强对脉络裂蛛网膜囊肿MRI表现的认识,提高对该病的诊断与鉴别诊断能力。方法结合文献研究脉络裂在不同MRI断面上的位置、走行及毗邻结构,对32例脉络裂蛛网膜囊肿的大小、形态、好发侧别及对周围结构的影响结合临床进行分析,并与海马周围其它囊性改变作鉴别对照。结果32例脉络裂囊肿于轴位、冠状位及矢状位MRI扫描像均可明确显示,而以冠状位显示最佳,其中26例(81.3%)位于右侧,发生率显着高于左侧(P<0.05). |

| Purpose To understand MRI manifestation of arachoid cyst in chroidal fissure through reviewing the anatomy of chroidal fissure in order to improve the ability of diagnosis and differential diagnosis of the disease.Methods The anatomy of chroical fissure on different image planes were studied with reference of papers.Thirty two cases of arachnoid cyst in chroidal fissure were analysed with the combination of clinical manifestations and compared with other similar cystic changes around hippocampus.Results All of the cysts were shown in transaxial,sagittal and coronal planes,but best displayed in coronal plane.Twenty six (81.3%) of them were seen in the right side,with a significant higher frequancy than the left side ( P <0.05).Conclusion Coronal plane is the best image plane in MRI diagnosis and differential diagnosis of arachnoid cyst in chroidal fissure. |
