CNS lymphoma follow up. There is no significant interval change in size of the lesions in the bilateral basal ganglia, right thalamus, left frontal periventricular white matter, and left cerebellar hemisphere. There is mild intrinsic high T1 associated with many of the lesions without appreciable enhancement. There is no significant interval change in the size and morphology of the ventricular system with unchanged coaptation of the right frontal horn. There is no midline shift or herniation. There is no evidence of intracranial hemorrhage or acute infarct. There is a faint left frontal lobe developmental venous anomaly. There has been interval resolution of the mucosal thickening and secretions in the bilateral maxillary and ethmoid sinuses. The skull and extracranial soft tissues are otherwise unchanged.
No significant interval change in the treated multifocal central nervous system lymphoma.
