 There are stable postsurgical findings related right parietal craniotomy with underlying encephalomalacia along the surgical approach extending to the ventricle and 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. There lateral and third ventricles appear to have slightly decreased in size. There is a small amount of unchanged chronic residual hemorrhage within the occipital horns. There is unchanged cystic encephalomalacia within the right basal ganglia. There is an unchanged 5 mm diameter left peritrigonal cystic lesion. There is no evidence of acute infarct or hemorrhage. The major cerebral flow voids are grossly intact. There is persistent mucosal thickening within the bilateral maxillary and ethmoid sinuses. The extracranial structures are unremarkable.
1.Stable postsurgical findings related to right lateral ventricle choroid plexus tumor removal without evidence of residual or recurrent tumor.2.Unchanged 5 mm wide cystic encephalomalacia versus prominent perivesicular space in the left peritrigonal region. Right basal ganglia cystic encephalomalacia is also unchanged. 3.Slight interval decrease in ventricular size.
