title: [Intrasellar arachnoid cysts. Two case reports and literature review].
abstract: Intrasellar arachnoid cysts are an uncommon pathology, with only a few cases reported in scientific literature. Their physiopathology is still unknown, with different hypothesis about their development. Differential diagnosis with other cystic sellar lesions is difficult. We report two cases of two intrasellar arachnoid cysts that were treated surgically using transsphenoidal approach and present a review of the literature.
