Sellar masses typically present in one or more ways:
●With neurologic symptoms, such as visual impairment or headache
●As an incidental finding on magnetic resonance imaging (MRI) performed for some other reason
●With hormonal abnormalities
This topic will review the causes, clinical manifestations, and evaluation of sellar masses. The clinical presentation and management of individual pituitary tumors and of hypopituitarism are discussed separately. (See appropriate topic reviews.)
