Tumors of the Sellar and Suprasellar Regions.

Tumors of the sellar, suprasellar, and parasellar regions are commonly encountered in pediatric neuroimaging. The regional anatomy is complex, and lesions of developmental, vascular, inflammatory/infective, and neoplastic origin occur. The 2021 WHO Classification of Tumors of the Central Nervous System recognized adamantinomatous craniopharyngioma and papillary craniopharyngioma as distinct tumor types, included pituitary blastoma as a new tumor, and included the terminology pituitary neuroendocrine tumor alongside pituitary adenomas. This article outlines the pediatric tumors of the sellar, suprasellar, and parasellar regions and describes their imaging appearance and the main non-neoplastic differential diagnoses.
