Pituitary macroadenoma. There is an enhancing pituitary mass that measures up to 16 mm in craniocaudal dimension. The mass abuts the optic apparatus, without significant mass effect. The tumor also extends into the cavernous sinuses bilaterally. The internal carotid artery flow voids are intact. The pituitary infundibulum is deviated to the left.
A pituitary mass that measures up to 16 mm in craniocaudal dimension is compatible with a macroadenoma.
