There is an unchanged subcentimeter enhancing focus within the right posterolateral aspect of the sella, which otherwise displays a partially empty configuration. The infundibulum is deviated slightly to the right. There is no mass effect upon the optic apparatus. Brain: There are subcentimeter defects in the right cerebellar hemisphere. There is also mild scattered nonspecific cerebral white matter T2 hyperintensity. There is no evidence of intracranial hemorrhage or acute infarct.
