This episode delves into the complex diagnostic and therapeutic challenges presented by functional multiple pituitary adenomas. We examine the concept of a 'decoy lesion' – a radiologically dominant but hormonally inactive tumor that can mislead surgical planning. This discussion is informed by the abstract of 'Decoy Lesion in Functional Multiple Pituitary Adenomas: Literature Review and Illustrative Cases on Diagnostic Pitfalls and Surgical Strategies,' published in World Neurosurgery in 2026. We explore the diagnostic pitfalls associated with these challenging presentations and discuss effective surgical strategies to ensure optimal patient outcomes.
