 Surgical changes including left frontal craniotomy and left frontal operculum tumor resection are again noted, with small left frontal surgical cavity with minimal associated susceptibility. Minimal increased FLAIR signal adjacent to the surgical cavity, as well as postsurgical dural thickening adjacent to the cavity, which are both unchanged. There are few tiny scattered foci of FLAIR signal abnormality in the subcortical white matter, which is nonspecific but likely represents minimal small vessel ischemic disease, similar to prior exam. The cisterns remain patent. There is no midline shift or mass effect. There are no areas of pathological enhancement. There is no diffusion abnormality. No extra-axial fluid collection is identified.Normal flow-voids are demonstrated in the major intracranial vascular structures. The midline structures and craniocervical junction are within normal limits.
Surgical changes of left frontal tumor resection with no evidence of residual or recurrent tumor.
