 There is no new intracranial mass or abnormal enhancement to suggest progression of metastatic disease. Again seen are postoperative findings related to right temporoparietal craniotomy for resection of metastatic lesion. There is hyperintense T2 signal abnormality in the treatment bed, which appears similar to prior and consistent with posttreatment change. Again seen are areas of encephalomalacia in the left parietal lobe, left basal ganglia and corona radiata, as well as a small focus in the right cerebellar hemisphere. There is ex vacuo dilatation of the left lateral ventricle. No hydrocephalus.There are scattered foci of hyperintense T2 signal abnormality within the periventricular and subcortical white matter, which likely represent combination of chronic small vessel ischemic disease and posttreatment-related change. Again seen is a punctate focus of susceptibility in the left cerebellar hemisphere which is compatible with a chronic microhemorrhage. There is no acute infarct. There is mild opacification of the right mastoid air cells. There are bilateral lens implants. Paranasal sinuses are grossly clear. No suspicious lesions involving the calvarium.
1. No new or recurrent metastatic lesions. 2. Multiple chronic supra- and infratentorial infarcts as above.
