Metastatic lung cancer, brain metastases status post right cerebellar lesion resection and RT and AP26113 therapy. There are postoperative findings in the posterior fossa with mild nonspecific linear enhancement along the anterior aspect of the right cerebellar hemisphere surgical margin. There is an unchanged subcentimeter partially cystic and partially enhancing lesion in the right middle frontal gyrus, measuring up to 5 x 13 mm overall. There are also unchanged punctate lesions in the right parietal lobe, left superior frontal gyrus, and paracentral gyrus. There is persistent vasogenic edema associated with the lesions. There is no evidence of new intracranial lesions. There is no evidence of intracranial hemorrhage 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. The orbits, skull, and scalp soft tissues are unchanged.
1. Postoperative findings in the posterior fossa with mild nonspecific linear enhancement along the right cerebellar hemisphere surgical margin. 2. Unchanged small supratentorial metastases.
