Rathke’s Cleft Cyst: Endoscopic Endonasal Transsphenoidal Approach

Fig. 10.1

Contrast-enhanced sellar MRI, sagittal image: typical appearance of a Rathke’s cleft cyst. The cyst has split the pituitary gland: the adenohypophysis has been moved and compressed anteriorly, and the neurohypophysis has been moved and compressed posteriorly. The cystic content does not show contrast enhancement
