 There are stable postsurgical findings related right parietal craniotomy with encephalomalacia along the surgical approach extending to the ventricle and bifrontal ventricular catheter tracks. The glomus of the right lateral ventricle choroid plexus is absent and there is no abnormal enhancement to suggest residual or recurrent tumor. The lateral and third ventricles appear to be unchanged in size. There is a small amount of unchanged minimal residual chronic blood products within the occipital horns. There is unchanged encephalomalacia within the posterior right basal ganglia. There are unchanged small cystic areas left peritrigonal white matter. There is no evidence of acute infarct. The major cerebral flow voids are grossly intact. There is persistent mucosal thickening within the bilateral maxillary and ethmoid sinuses. The extracranial structures are unchanged.
1.Stable postsurgical findings related to right lateral ventricle choroid plexus tumor removal without evidence of gross residual or recurrent tumor.2.Unchanged small cystic areas in the left peritrigonal region may represent prominent perivascular spaces. 3.Right posterior basal ganglia encephalomalacia is unchanged.
