Abstract Objective: To discuss the value of MRI in the diagnosis of choroidal fissure cyst. Meterials and Methods: MRI findings of choroidal fissure cyst in 19 patients were analyzed retrospectively. Axial CT scanning had been applied in 8 cases, and 5 cases accepted further MRI enhanced scanning. Results: All lesions located at the area of choroidal fissure, 17 cases were in the right and 2 cases in the left. They all were single lesion. The size of the biggest lesion was 20mm×28mm and the smallest was 3mm×5mm. Round or long oval shape was seen on axial imaging, communicated with ambient cistern or qaudrigeminal cistern, with no associated edema. Gd-DTPA was performed in 5 cases and revealed no evidence of enhancement. Conclusion: MR imaging with multiple planes and sequences, and can see the choroidal fissure clearly. MR is better than CT in diagnosing choroidal fissure cyst.
