 Again seen are postsurgical changes of left temporal craniotomy for resection of left temporal lobe metastatic lesion. There is unchanged T2/FLAIR hyperintensity along the left temporal resection cavity consistent with gliosis. There is minimal enhancement around the resection cavity which is consistent 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 foci of T2/FLAIR hyperintensity in the white matter are nonspecific but 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.Post-treatment changes without evidence of residual or recurrent tumor at the left temporal resection cavity. 2.No new intracranial metastasis.
