 There is no restricted diffusion to suggest acute ischemic infarction. Again noted are postsurgical changes of the right frontal partial lobectomy for tumor resection. The right frontal surgical cavity with surrounding T2/FLAIR hyperintensity is unchanged. There is associated ex vacuo dilatation of the right frontal horn. There is stable mild epidural thickening and enhancement subjacent to the craniotomy, an expected postsurgical change. There is no abnormal enhancement in the parenchyma. The remainder of the brain parenchyma is negative for new signal abnormality. There is no midline shift or herniation. The major cerebral flow voids are intact. The paranasal sinuses are unremarkable. The midline structures and craniocervical junction are within normal limits.
Stable postsurgical changes in the right frontal lobe with no evidence of residual or recurrent tumor.
