Elevated prolactin, rule out prolactinoma. Pituitary: There appears to be a focus of hypoenhancement in the posterior left adenohypophysis that measures up to 2 mm. Otherwise, the pituitary gland is not enlarged. The posterior pituitary bright spot is intact. The infundibulum is intact and situated in the midline. The optic apparatus and cavernous sinuses are intact. Brain: There is no evidence of intracranial hemorrhage or acute infarct. The brain parenchyma appears unremarkable. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, and scalp soft tissues are grossly unremarkable. There is extensive mucosal thickening in the sphenoid sinuses.
An apparent punctate focus of hypoenhancement in the posterior left adenohypophysis may represent a microadenoma.
