GBM resected in 2/15 on TMZ Right frontal oval resection cavity is not significantly changed in size measuring approximately 59 x 36 mm in oblique cross-sectional dimensions (series 801, image 18). There is a thin rim of hemosiderin and minimal peripheral FLAIR signal surrounding the resection cavity. There are subcortical foci of FLAIR hyperintensity in the right anterior temporal lobe that are stable and likely related to areas of gliosis, perhaps post-operative. There is no abnormal enhancement in the brain. Dural enhancement and thickening at the craniotomy site is postoperative in etiology. No significant interval change in relative cerebral blood volume around the resection cavity or elsewhere in the brain to suggest tumor recurrence. There is no significant interval change in size of the small extra-axial fluid collection along the undersurface of the craniotomy flap. Mild effacement of the right frontal horn is unchanged. No midline shift.Perfusion imaging does not demonstrate any evidence of hyperperfusion along the resection cavity.
Stable postsurgical changes without evidence of tumor recurrence.
