 There are unchanged posttreatment findings including right temporal occipital craniotomy with underlying resection cavity, associated foci of susceptibility effect, minimal residual linear enhancement, and unchanged moderate confluent T2 hyperintensity surrounding the resection cavity. There is no increased relative CBV in the postoperative region. There are no separate/new areas of suspicious enhancement. There is an unchanged punctate focus of high diffusion signal with corresponding high ADC signal and small slightly more prominent focus of high T2 signal in the right brachium pontis on series 401 image 7; there is slightly greater prominence of the high T2 signal focus in the right brachium pontis felt to represent evolving encephalomalacia from old tiny infarct. There is no acute infarct. The ventricles are unchanged with ex vacuo dilatation of the right occipital horn. There is no midline shift or herniation. There is mild unchanged T2 hyperintense signal in the right mastoid air cells. There is mild bilateral maxillary sinus mucosal thickening. The skull and extracranial soft tissues are otherwise unremarkable.
Stable postoperative findings without evidence of tumor progression.
