Elevated prolactin. Pituitary: There appears to be a punctate hypoenhancing focus in the right pituitary lobe. The pituitary gland is otherwise not enlarged, measuring up to 6 mm in craniocaudal dimension. The posterior pituitary bright spot and stalk are intact. The cavernous sinuses and optic apparatus are unremarkable. 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, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
An apparent punctate hypoenhancing focus in the right pituitary lobe may represent a microadenoma or physiologic variant.
