61-year-old male with acute mental status changes. Now with change in pupil sizes, right pupil pinpoint. Neither pupil reactive to light. Concern for herniation. There is significant beam hardening artifact affecting the posterior fossa which limits the evaluation. Since the prior study, there is suggestion of decreased density in the left cerebellar hemisphere which may be due to ischemia. The basilar cisterns are less well visualized. An MRI is recommended for further characterization of this region.Other findings appear similar to the prior CT from earlier the same day.These findings were discussed with Dr. Harshal Sheth at the time of interpretation.
Limited examination, but new decreased density in the left cerebellar hemisphere which may be due to ischemia. An MRI is recommended for further characterization of this region.
