Case contributed by A.Prof Frank Gaillard


Patient presented with acute headache.

Case Discussion

Pituitary apoplexy is an acute clinical syndrome caused by either hemorrhage or infarction of the pituitary gland. Although variable, it typically comprises of headache, visual deficits, ophthalmoplegia, and altered mental status. An existing pituitary macroadenoma is usually present (60-90%) but it can occur with healthy glands in few isolated cases.

The patient had the diagnosis confirmed histologically after transsphenoidal resection.
