Metastatic lung cancer, brain metastases status post right cerebellar lesion resection and RT and AP26113 therapy. There are postoperative findings in the posterior fossa without evidence of right cerebellar tumor recurrence. There is an unchanged subcentimeter partially cystic and partially enhancing lesion with mild surrounding T2 hyperintensity in the right middle frontal gyrus. There is also an unchanged punctate intrinsically T1 hyperintense lesion in the left superior frontal gyrus. 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. There is moderate mucosal thickening in the bilateral maxillary sinuses and a retention cyst in the right sphenoid sinus.
1. Unchanged postoperative findings in the posterior fossa without evidence of right cerebellar tumor recurrence. 2. Unchanged small bilateral frontal lobe treated metastases.
