Pediatric sellar and suprasellar lesions

Masses arising in the sella turcica and the suprasellar region are common in children. The type and frequency of the various lesions encountered in childhood differ from the adult presentation. This article reviews the embryology of the pituitary gland and its normal appearance in childhood as well as the imaging and clinical findings of the common and some of the uncommon lesions arising in the sella turcica, the pituitary stalk, the suprasellar cistern and the lower third ventricle in the pediatric population.
