Metastatic thyroid cancer, status post resection April 20, 2014 Again seen are postsurgical findings related to a right frontotemporal craniotomy. There is no significant change in appearance of the posterior inferior frontal gyrus resection cavity with evidence of chronic blood products and intrinsic T1 hyperintensity. Unchanged surrounding FLAIR hyperintensity compatible with edema and/or gliosis. No significant mass effect. No new enhancement is seen at the resection cavity to suggest local recurrence.There is a punctate 2 mm enhancing nodule involving the left superior cerebellar hemisphere, best seen on series 10 with gadolinium 3-D FSPGR image 50, and not seen previously. No significant associated edema.Unchanged nonspecific punctate focus of susceptibility effect in the right basal ganglia. The ventricles and sulci are unchanged. There is no midline shift or mass effect. There is no evidence of acute infarction. There is an unchanged subcentimeter posterior nasopharynx retention cyst or Thornwaldt cyst. There is unchanged partially imaged asymmetric hyperenhancement of the left parotid gland, which may be treatment-related.
1. Post-treatment findings related to resection of a right frontal lobe metastasis without evidence of local tumor recurrence. There is however a 2 mm enhancing nodule involving the left superior cerebellar hemisphere which was not seen previously and suspicious for new metastatic focus. 2. No significant edema or mass effect.
