61-year-old male with h/o glioblastoma presents with weakness. Evaluate for intracranial bleed. There is no evidence of intracranial hemorrhage, mass, or edema. Post-surgical changes of a right-sided craniotomy and right temporal resection with encephalomalacia are similar to prior. Extensive confluent hypoattenuation involving primarily the white matter of the right cerebral hemisphere is similar to prior. Based on recent MRI findings, this is compatible with post-radiation changes.Hypoattenuating lesions in the left thalamus is seen on prior MRI and is compatible with lacunar infarct. It demonstrates increased hypodensity, compatible with expected evolutional changes. The ventricles and basal cisterns are normal in size and configuration.The calvaria and skull base are radiographically normal. The visualized paranasal sinuses and mastoid air cells are normally pneumatized.
No acute intracranial hemorrhage. Evolutionary change of lacunar infarct at left thalamus. Post-surgical and post-treatment changes similar to prior.
