Clinical question: status post craniotomy. Signs and symptoms: Same Nonenhanced head CT:Extensive postoperative changes of a left frontal -- temporal craniotomy is again identified. There is no definite evidence of any interval change.Small area of low-attenuation along the anterior aspect of the left temporal lobe is better visualized than prior study. This finding may represent widened left sylvian fissure due to recent surgical intervention. Possibility of focal cortical edema cannot be entirely ruled out. Please correlate with exam and if there is clinical concern for ischemic change recommend an MRI study.There is no evidence of interval hemorrhage since prior study. No evidence of hydrocephalus. Minimal midline shift to the right of approximately 3 mm is again noted with no change. Expected postoperative changes of intracranial air and small epidural blood/fluid collection under the craniotomy flap is again noted.
No definitive interval change since prior study. Please see above comments.
