Abstract:
Objective To study normal imaging features of choroid fissure and to improve the ability of diagnosis of choroid fissureneuroepithelial cyst.Methods The MR manifestations of choroid fissure were studied by comparing general brain specimen with MR images of normal brains.The analysis of CT and MRI findings of choroid fissure neuroepithelial cysts in 14 cases were also conducted.Results The whole choroid fissure was clearly displayed as fissures full of cerebrospinal fluid on MRI.Cysts were shown round or ellapse foci with sharpmargins and homogeneous low density on CT or cerebrospinal fluid-like signal intensity on MRI.There was no enhanced contrast or nodramatic changes in follow-up studies.Conclusion The recognization of MR anatomy of choroid fissure and imaging manifestations ofchoroid fissure neuroepithelial cysts can improve the ability of diagnosis and differential diagnosis of cysts.
