Metastatic thyroid cancer with single right occipital met status post resection and SRS: surveillance MRI. There are postoperative findings related to right occipital craniotomy. There is continued slight decrease in dural thickening along the and posterior falx cerebri and parenchymal enhancement within the right paramedian occipital lobe resection cavity. There is persistent confluent T2 hyperintensity along the margins of this resection cavity. No new abnormal intracranial enhancement is identified. There is an unchanged background of nonspecific cerebral white matter T2 hyperintensity, which may represent chronic small vessel ischemic disease. There is no evidence of acute intracranial hemorrhage or acute cerebral infarct. The ventricles and basal cisterns are unchanged in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. There are bilateral lens implants.
Slight interval evolution of treatment findings in the right occipital region without evidence of new intracranial metastases.
