Head and neck cancer with brain metastasis status post SRS: 3 month follow up. There has been decrease in size of the left cerebellar hemisphere lesion with susceptibility effect, which measures up to 8 mm, as opposed to 18 mm in October 2014. There is no discernible surrounding vasogenic edema. There is no evidence of acute infarct. There are a few nonspecific scattered punctate foci of T2 hyperintensity in the white matter. There is no abnormal intracranial enhancement. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. There are bilateral lens implants. There appears to be fluid within the right maxillary sinus. There are post-treatment findings in the partially-imaged upper neck and denervation atrophy of the right tongue.
1. Interval decrease in size of the treated left cerebellar metastasis.2. Findings suggestive of right maxillary acute sinusitis.
