Craniopharyngioma is a histologically benign, extra-axial, slow-growing tumor that predominately involves the sella and suprasellar space. Craniopharyngiomas are dysodontogenic epithelial tumors derived from the Rathke cleft, which is the embryonal precursor to the adenohypophysis. Changes in signal intensity vary on T1-weighted images depending on the cystic contents, which can appear hyperintense if they have a high protein, blood product, and/or cholesterol content.
