Right frontal GBM, IDH wt, MGMT promoter unmethylated; s/p biopsy, RT/TMZ, TMZ+TTF x1 cycle, craniotomy with extensive resection (7/19/16). There are findings related to right frontoparietal craniotomy with right posterior frontal lobe paramedian resection cavity. There is decreased enhancement along the margins of the resection cavity, which is now negligible. There is unchanged confluent high T2 signal surrounding vasogenic edema. A few scattered foci of T2 hyperintensity elsewhere in the cerebral white matter are nonspecific. There is no evidence of acute ischemia or intracranial hemorrhage. There is no midline shift. The skull and extracranial structures are unchanged.
Further interval decreased enhancement surrounding the right paramedian frontal lobe resection cavity.
