title: Choroid plexus papilloma originating in the sella turcica--case report.
abstract: A 51-year-old female presented with a rare case of choroid plexus papilloma originating in the sella turcica manifesting as headaches that was not readily distinguishable preoperatively from pituitary adenoma. Head magnetic resonance imaging revealed a tumor extending from the sella turcica to the suprasellar cistern. The tumor was removed via an endonasal transsphenoidal approach. Histological examination indicated a papillary structure covered with a layer of columnar epithelial cells that resembled normal choroid plexus. These findings, together with immunohistochemistry, led to a diagnosis of choroid plexus papilloma.
