Recurrent pituitary adenoma, transsphenoidal resection, 6 month follow up. Pituitary: There are postoperative findings related to transsphenoidal surgery. There is an enhancing mass in the pituitary mass that encases the right cavernous carotid artery and extends into the suprasellar cistern, where there is mass effect upon the optic apparatus, which displays volume loss. The mass measures approximately 24 AP x 32 RL x 21 SI mm, previously 23 AP x 32 RL x 20 SI mm, and the tumor has gradually increased in size over the course of several years. The infundibulum is deviated to the left.Brain: There is no evidence of intracranial hemorrhage or acute infarct. There is unchanged nonspecific mild cerebral white matter T2 hyperintensity. The ventricles are unchanged in size and configuration. There is no midline shift or herniation. The skull and extracranial soft tissues are unchanged, including postoperative findings in the right parotid region.
