For Research: GBM s/p resection with Ziopharm trial: surveillance. There are postoperative findings related to prior left temporal lobe tumor resection, with evolving blood products in the surgical bed. There is perhaps slight interval decrease in size of the heterogeneously enhancing nodular lesion in the posterior left temporal lobe, anterior to the resection cavity, measuring 15 x 18 mm, previously 18 x 20 mm. The is persistent extensive surrounding confluent T2 hyperintensity, with slight extension across the corpus callosum, but overall slightly decreased associated swelling. There is also persistent diffuse linear enhancement along the margins of the resection cavity. There is no significant midline shift or herniation. The ventricles are unchanged in appearance. There are postoperative findings related to sinonasal surgery and diffuse paranasal sinus mucosal thickening.
Postoperative findings related to prior left temporal lobe tumor resection with what appears to be slight interval decrease in size of the treated residual tumor and perhaps slightly decreased surrounding edema.
