 There is a redemonstration of a right frontal burr hole.There are FLAIR/T2 hyperintensities in the subcortical and the periventricular white matter, and the right centrum semiovale, which are nonspecific, but most likely consistent with chronic small vessel ischemic changes. There are a few foci of dark susceptibility signal in the left parietal, bilateral basal ganglia, and the temporal lobes, consistent with blood products from old microhemorrhages.There is no evidence of acute hemorrhage, mass effect, or edema. The ventricular system is stable.Findings are seen compatible with prior transsphenoidal pituitary surgery. Irregular enhancing tissue within the sella and perhaps also the right cavernous sinus appears similar to prior exams.An oval nodule is again seen within the right parotid gland without change. The extracranial tissues are otherwise unremarkable.There is hypoplastic right maxillary sinus.
1. No evidence to suggest recurrent primary CNS lymphoma.2. Stable appearance of the postoperative sella.3. Stable nonspecific right parotid nodule.
