 There are unchanged multiple foci of T2 hyperintensity within the supratentorial white matter. There multiple unchanged foci susceptibility effect throughout the cerebral and cerebellar hemispheres, mostly likely secondary to radiotherapy. There is minimal unchanged punctate enhancement within the previously treated left precentral gyrus lesion. There is otherwise no appreciable corresponding abnormal enhancement . There is no evidence of acute infarct. The ventricles and basal cisterns are unchanged in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are grossly intact. The skull, paranasal sinuses, and scalp soft tissues are unremarkable.
No significant change in the post-radiotherapy appearance of the brain, including treated brain metastases.
