Reason: eval interval changes History: weakness Nonenhanced CT of brain:Examination again demonstrate large area of left frontal -- temporal craniectomy with resultant slight bulge of brain parenchyma through the bony defect. The entire left anterior temporal lobe, left inferior frontal lobe has uniformly high density compared to the rest of brain parenchyma which remains stable and is concerning for petechial hemorrhage. A follow-up with an MRI is recommended. This finding remains stable since prior exam. Subtle encephalomalacia/edema in the left basal ganglia is again noted with no change. Extra-axial fluid density at the site of craniectomy and extension posterior to the posterior edge of craniectomy is again noted. There is slight increase in the fluid collection at this site since prior exam.
1.No definitive evidence of new intracranial findings since prior study. Please see above comments.2.Slight interval increase in the extra-axial fluid collection at the craniectomy site with extension posterior to the dorsal edge of craniectomy.
