History of pituitary adenoma, with recent blurred vision in both eyes over last month. Pituitary: There appears to be a punctate focus of hypoenhancement in the posterior right pituitary lobe. Otherwise, the pituitary gland is not enlarged and there is no evidence of pituitary macroadenoma. The infundibulum and optic apparent are intact. Brain: There is no evidence of intracranial hemorrhage, mass, or acute infarct. The brain parenchyma appears unremarkable. There is no abnormal intracranial enhancement. 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.
1. Apparent punctate focus of hypoenhancement in the posterior right pituitary lobe may represent artifact or perhaps a microadenoma, but no evidence of macroadenoma or other mass lesions compromising the optic apparatus.2. No evidence of intracranial hemorrhage, mass, or acute infarct.
