Pituitary apoplexy is an uncommon but well-known condition that leads to acute deteriorated neurological and endocrinal deficits. However, subarachnoid hemorrhage and intraventricular hemorrhage resulting from pituitary apoplexy are rarely reported in the literature. We reported a 75-year-old female presenting with severe headache and visual impairment. Magnetic resonance images of the brain revealed a pituitary macroadenoma. Acute deteriorated neurological deficits developed after admission during the correction of hyponatremia. The computed tomographic scan of the brain revealed pituitary apoplexy with diffuse subarachnoid hemorrhage and intraventricular hemorrhage. The relevant literature is reviewed.
