50 year-old male with headache. Evaluate for postoperative hemorrhage. Postoperative changes status post left temporal craniotomy in the region of dural thickening seen on recent MRI, with small amount of pneumocephalus and overlying subgaleal edema and hematoma. Minimal high density is seen at the surgical cavity compatible with hemorrhage. There is mild effacement of the sylvian fissure on the left, with no additional evidence of mass effect.Encephalomalacia is again seen in the left basal ganglia/subcortical white matter, unchanged from the prior exam. The remainder of the cerebral and cerebellar hemispheres and brainstem demonstrate normal morphology and density. The ventricles are midline, with normal volume and morphology. There is no midline shift.Postoperative changes status post bitemporal craniotomies. The visualized paranasal sinuses and mastoid air cells are normally pneumatized.
Expected postoperative changes status post left temporal craniotomy.
