Pituitary macroadenomas are the most common suprasellar mass in adults. Pituitary adenomas are lesions greater than 10 mm in size and are approximately twice as common as pituitary microadenomas.
Identifying the posterior pituitary bright spot is important to identify and mention in reports to avoid diabetes insipidus.
This patient underwent a transsphenoidal hypophysectomy.
