Abstract：Objective: To explore the neuroradiological features of Rathke’s cleft cyst. Materials and Methods: Fifteen cases of Rathke’s cleft cysts proved pathologically received plain and contrast-enhanced MRI scan. Additionally, of the 15 cases, 12 cases received plain CT scan. CT and MRI image features were analyzed. Results: Eight cases were entirely intrasellar, 3 were intrasellar with suprasellar extensions, and 4 were suprasellar. Hypo-, iso-, hyper-density mass were found in Rathke’s cleft cyst on CT scan. Rathke’s cleft cysts may have different MRI signal characteristics according to the component of the cysts. Commonly no enhancement can be seen, but a small amount has enhanced wall. Conclusion: Rathke’s cleft cysts have various findings in imaging, CT and MRI are valuable examinations. But the diagnosis must be given by pathological examination.
