Description Pituitary apoplexy is a clinical syndrome involving either hemorrhage or infarction of a pituitary tumor, which classically presents with a severe acute headache, nausea and visual deficits2. However, several studies have found that the majority of cases involving either radiographic or surgical evidence of hemorrhage or infarction of a pituitary tumor were not associated with these symptoms1,3. This asymptomatic presentation is known as silent or subclinical apoplexy (SPA).
