Pituitary adenoma, history of resection. Evaluate change to residual tumor. There are postoperative findings related to transphenoidal surgery. There is no significant interval change in size of the lobulated enhancing left sellar and suprasellar mass, which measures approximately 15 AP x 10 RL x 13 SI mm. There is persistent mild mass effect upon the left lateral aspect of the optic apparatus, which otherwise demonstrates normal signal characteristics. There is no evidence of intracranial hemorrhage or acute infarct. The brain parenchyma appears unremarkable. The ventricles are stable in size and configuration. There is no midline shift or herniation.
Persistent lobulated left sellar and suprasellar residual macroadenoma with persistent mild mass effect upon the left lateral aspect of the optic apparatus.
