 Stable postsurgical changes of left temporal craniotomy for resection of left temporal lobe metastatic lesion. Marked improvement of surrounding edema. Decrease in size of resection cavity. Minimal enhancement around the resection cavity compatible with treatment change. No evidence of residual or recurrent tumor at the resection cavity. There is no abnormal enhancement within the remainder of the brain to suggest new lesions. There are no masses, mass effect or hydrocephalus. There is no evidence for intracranial hemorrhage or diffusion-weighted abnormalities. Scattered white matter signal abnormality compatible with mild chronic small vessel ischemic disease. Flow voids are present within the major vessels indicating patency. The paranasal sinuses and mastoid air cells are clear. The orbits are unremarkable.
1.Evolving post-treatment changes without evidence of residual or recurrent tumor at the left temporal resection cavity. 2.No evidence of new intracranial metastasis.
