Status post suboccipital craniotomy with partially visualized fluid collection in craniotomy site not significantly changed since post recent MRI.Metallic coils are present in proximal right MCA territory, with significant metallic streak artifact obscuring adjacent structures at this level.Focal hypodensity in right parietal lobe consistent with encephalomalacia from prior hemorrhage is noted, with interval evolution since 6/2012 CT. Encephalomalacia also noted in left frontal lobe and superior left cerebellum, unchanged.There is no evidence of acute intracranial hemorrhage, mass or edema. No hydrocephalus.The ventricles and basal cisterns are normal in size and configuration.The visualized paranasal sinuses and mastoid air cells are normally pneumatized.
