Cystic Degeneration within Non-functioning Pituitary Macroadenoma: Pathogenesis, Differential diagnosis and Surgical outcome with representative Case Illustration

Abstract

Cystic pituitary adenomas constitute diagnostic as well as therapeutic challenges in terms of accurate preoperative diagnosis, per operative incomplete removal, CSF leakage and recurrence. Thereby, understanding the pathogenesis of cyst formation, neuroimaging criteria of the cysts in different cystic sellar masses are important in preoperative counselling, operative strategy and predicting outcome.
