Subacute pituitary apoplexy: MR and CT appearance

Abstract

We report three cases of subacute hemorrhage into a pituitary adenoma. Two patients each had visual disturbance and hypopituitarism treated with corticosteroids. No patient received bromocriptine. Because it is more exact than CT in displaying the metabolic products of hemorrhage, magnetic resonance is the preferred modality for radiographic investigation of subacute or chronic pituitary apoplexy in patients with prolonged headache and visual disturbance.
