Background:
Rathke's cleft cyst is a rare benign sellar lesion. The exact preoperative diagnosis of this lesion by clinical and radiological features is difficult. Hence it is often misdiagnosed as craniopharyngioma.
Aim:
To identify the radiological pointers for pre operative diagnosis of Rathke's cleft cyst.
Materials And Methods:
This study presents the details of nine patients who were operated in our institution between 1998 and 2008. Radiological and histopathological variations were studied.
Results:
The possibility of Rathke's cleft cyst was considered pre operatively in one patient only. On reviewing the images, characteristic imaging findings were observed in a few cases.
Conclusion:
As minimally invasive trans-sphenoidal approach is sufficient for treating these lesions, pre operative diagnosis is important.
