Rathke cleft cyst


Given the imaging appearance (CSF intensity in ventral pituitary), this lesion likely represents a Rathke cleft cyst. The patient was also incidentally found to have right cerebellar ectopia.

The patient has been following up with endocrinology as an outpatient. Surgery is planned due to the symptomatic nature of the lesion.
