Pituitary adenoma. Pituitary: There is a pituitary mass with suprasellar extension, which measures up to 22 mm in the craniocaudal dimension and 20 mm in the transverse dimension. The tumor protrudes into the medial compartment of the left cavernous sinus. The tumor also abuts the optic chiasm.Brain: There is no evidence of intracranial hemorrhage or acute infarct. There are mild scattered foci of T2 hyperintensity in the cerebral white matter, which may represent chronic small vessel ischemic disease. There is encephalomalacia in the right inferior cerebellar hemisphere and right pons. The ventricles are unchanged in size and configuration, including cavum septum pellucidum and vergae. 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.
