Abstract
Pituitary apoplexy is a rare, life-threatening complication that may occur after coronary artery bypass graft surgery for patients with pituitary adenomas. The dynamics of cardiopulmonary bypass may contribute to a sudden expansion of silent pituitary adenomas and result in the compression of surrounding structures. A range of clinical features have been described, and the condition requires prompt diagnosis and treatment to prevent further complications. Herein, we present an uncomplicated case highlighting the importance of diagnosing pituitary apoplexy, ensuring high alertness to the condition, so as to prevent life-threatening tragedy due to missed diagnosis.
