Female, 37 years old, history of right parietal grade 3 oligodendroglioma status post resection, radiation and chemotherapy. Again seen are postsurgical changes of right parietal craniotomy for tumor resection. The resection cavity involving the inferior parietal lobule with surrounding T2/FLAIR hyperintensity remains unchanged with signal abnormality extending into the posterior temporal lobe also similar to prior. No new T2/FLAIR hyperintensity, mass effect, or suspicious enhancement is appreciated. Intrinsic T1 hyperintensity and susceptibility effect are again seen consistent with posttreatment change.There is a small developmental venous anomaly within the right thalamus. Mild ex vacuo dilatation of the right lateral ventricle is again seen. Remainder of the brain parenchyma is unremarkable without evidence of new infarct, hemorrhage, mass, or mass effect. No hydrocephalus. Aside from postsurgical changes, calvarium and extracranial soft tissues are unremarkable.
Posttreatment changes in the right temporoparietal lobes remain unchanged. No evidence of tumor progression.
