Abstract
BACKGROUND: Giant pituitary adenomas are characterized by their large size and potential to invade parasellar and suprasellar regions leading to visual decline and hypopituitarism. Thus, they remain a significant surgical challenge, and gross total removal is only achieved in the minority of cases. METHOD: We aim to describe the key surgical steps for endoscopic extra-capsular resection of a giant pituitary adenoma with the aim of achieving complete tumor resection with description of the relevant surgical anatomy, indications and limitations. CONCLUSION: Endoscopic extra-capsular resection of giant pituitary tumors when feasible allows for complete tumor resection, early identification of the gland and avoidance of manipulation of the optic apparatus.
