Abstract
Objective:To analyze the MRI findings of Rathke's cleft cyst and to improve the level of MRI diagnosis and differential diagnosis in rathke's cleft.Method:The clinical and MRI data of 12 patients with Rathke's cleft cyst proved by clinical follow-up and surgical pathology were collected.All patients received MRI plain scanning and 11 patients received contrast-enhanced scanning at the same time.The location,size,shape,margin and MRI findings of Rathke's cleft cyst were analyzed.Result:The maximal diameter of the 12 rathke's cleft cysts was less than 10 mm.There were 10 cysts in the intrasella and 2 cysts in the suprasellar.The margins of all cysts were clear.11 cysts were regular in shape and 1 cyst was lobular.There were diverse signals on T1WI and T2WI.The low signal on T1WI and high signal on T2WI were seen in 6 Rathke's cleft cysts.After enhancement scan in 11 patients,only 1 cyst was enhanced peripherally and the other 10 cysts were not enhanced.The intracystic nodule and bottom sediment did not appear in all Rathke's cleft cysts.Conclusion:The MRI appearance of intrasellar Rathke's cleft cysts is more characteristic in diagnosis.However,the suprasellar Rathke's cleft cyst is seldom seen,it often needs differential diagnosis from the other cystic lesions in the sellar region.关键词
