Abstract
Etiology and pathogenesis of empty cella syndrome remains undetermined in some cases (primary or idiopathic type), while in others it is related to treatment of pituitary and parasellar disease (secondary type). Ten patients with empty sellae, secondary to treatment of pituitary adenomas (five cases), granulomas (three cases), craniopharyngioma (one case), and optic glioma (one case) are presented. Pathogenesis of empty sella is discussed and the importance of neuroradiologic evaluation of this syndrome is stressed.
