 Redemonstrated are stable postsurgical findings related right parietal craniotomy with underlying encephalomalacia along the surgical approach extending to the ventricle. As before, there are bifrontal ventricular catheter tracks. The glomus of the right lateral ventricle choroid plexus is surgically absent and there is no abnormal enhancement to suggest residual or recurrent tumor. Ventricular sizes are unchanged. Unchanged chronic residual hemosiderin within the occipital horns is again noted. There is stable cystic encephalomalacia within the right basal ganglia. A 5 mm diameter left peritrigonal cystic lesion is somewhat less apparent and may be related to perivascular spaces. There is no evidence of acute infarct or hemorrhage. The major cerebral flow voids are grossly intact. Mucosal thickening within the bilateral maxillary and ethmoid sinuses has resolved. The extracranial structures are unremarkable.
