History of anaplastic astrocytoma s/p resection and RT/TMZ. Off all treatment now. There are postoperative findings of a right frontal craniotomy. Area of T2 hyperintensity centered in the right superior frontal gyrus consistent with a postoperative cavity is unchanged from the prior exam. Surrounding T2 signal is unchanged in extent. T2 hyperintense signal in the periventricular region, right greater than left, is also unchanged. Susceptibility in the resection cavity likely reflects old blood products. No new areas of abnormal T2 signal. A thin branching focus of enhancement along the resection cavity is stable and likely represents scar tissue. No new areas of abnormal enhancement.No evidence of diffusion restriction. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
Stable surgical and treatment related changes without evidence of progressive disease.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
