Transsphenoidal resection for a pituitary mass. There are postoperative findings related to transsphenoidal surgery. There is an enhancing mass that measures up to 37 mm within the sella with extension into the left cavernous sinus and parasellar region and suprasellar cistern. There is resultant encasement of the left internal carotid artery without significant narrowing of the flow void. There is also mass effect upon the right prechiasmatic optic nerve, but not the optic chiasm. The mass may also abut the left prechiasmatic optic nerve, without associated significant mass effect. The infundibulum is intact, but deviated to the right. There are secretions within the constricted sphenoid sinuses. There is no evidence of intracranial hemorrhage or acute infarct. The brain parenchyma appears unremarkable. There is no abnormal intracranial enhancement. The ventricles are unchanged in size and configuration. There is a subcentimeter left parietal scalp mass.
Residual pituitary macroadenoma with mass effect upon the right prechiasmatic optic nerve and encasement of the left internal carotid artery.
