Methods Characteristic MSCT findings in 13 patients with archnoid cyst in choroidal fissure were retrospectively analyzed and the correlation between MSCT imaging and clinical symptom was discussed. Results The cysts were situated within the choroidal fissure in all cases, they all were single lesion，representing as cystic lesion with clearborder , no detectable soft tissue mass in the cyst wall or adjacent area, homogenous density identical to CSF, with the average size of 0.7cmtimes;0.8cmtimes;1.1cm, and no associated edema. Conclusion Archnoid cyst in chroidal fissure of the brain is a benign and congenital developmental abnormality, and has no clinical symptom in common. Combined with the use of the methods of routine axis scan of MSCT and MPR technology may play an important role in the correct diagnosis of archnoid cyst in choroidal fissure. The correct recognization of the MSCT imaging manifestations of archnoid cyst in choroidal fissure can improve the ability of diagnosis. 【Key words】　choroidal fissure archnoid cyst tomography X-ray computed 脉络膜裂蛛网膜囊肿(Archnoid Cy
