 Redemonstrated are remote post-operative findings related to a left parieto-occipital craniotomy for tumor resection. There is unchanged T2/FLAIR hyperintensity surrounding the resection cavity as well as unchanged periventricular T2/FLAIR hyperintensity, left side more than right. There is no pathologic enhancement. There is a thin rim of T1 shortening and susceptibility artifact along the periphery of the surgical cavity, consistent with blood degradation products and/or mineralization. There is an unchanged punctate focus of susceptibility effect within the left frontal white matter, consistent with hemosiderin deposition from chronic microhemorrhage. There is no evidence of acute intracranial hemorrhage or acute infarct. The ventricles and basal cisterns are unchanged in size and configuration, including mild ex vacuo dilatation of the left ventricular atrium. There is no midline shift or herniation. The skull and extracranial soft tissues are unremarkable.
Stable post-operative findings related to a remote left parieto-occipital craniotomy for tumor resection and surrounding T2/FLAIR hyperintensity consistent with treatment changes. No evidence of tumor progression.
