DIAGNOSIS OF RATHKE′S CYSTS WITH CT AND MRI (REPORT OF 6 CASES) / 解放军医学杂志

To promote understanding and improve diagnostic level of Rathke′s cysts with CT and MRI,crosscheck analysis was performed between CT,MRI and operative pathology was done in 6 cases.Results: It was misdiagnosed as cranio pharyngioma,hypophysoma and cholesteatoma in CT and MRI before operation.Oval and irregular cystic low density was showed in CT in 4,oval iso density and higher density in 1,respectively,and line like reinforcement of the cystal wall in 2 after intensification.Oval and oval like low signals were showed in 3 and isosignals in 1 on T 1 weighted images of MRI and high signals with clear edge on T 2 weighted images.It suggested that the diagnostic value of MRI was superior to that of CT in Rathke′s cysts.
