History of metastatic lung cancer. The images are degraded by patient motion. There are postoperative findings related to left occipital craniotomy and lesionectomy. There is persistent confluent high T2 signal surrounding the resection cavity, but no evidence of abnormal intracranial enhancement that might otherwise suggest the presence of neoplasm. There is also unchanged confluent cerebral white matter T2 hyperintensity elsewhere, particularly in the corona radiata, which may be treatment-related and/or chronic small vessel ischemic disease. There is no evidence of intracranial hemorrhage, mass, or acute 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 is a small left maxillary sinus retention cyst. There is a punctate cystic focus in the skin of the left cheek. The orbits are unremarkable.
Stable post-treatment findings without evidence of recurrent or new intracranial metastases.
