Cerebral vasospasm as a consequence of pituitary apoplexy: illustrative case.

Background: Cerebral vasospasm is a rare but devastating complication following pituitary apoplexy. Cerebral vasospasm is often associated with subarachnoid hemorrhage (SAH), and early detection is crucial for proper management.

Observations: The authors present a case of cerebral vasospasm after endoscopic endonasal transsphenoid surgery (EETS) in a patient with pituitary apoplexy secondary to pituitary adenoma.
