28 year old male; evaluate for CVA. Subtle area of low attenuation within the brainstem likely represents artifact. A separate subtle area of low attenuation is noted in the right thalamus/posterior limb of the internal capsule; if acute infarct is suspected, recommend MRI or repeat examination to further evaluate.There is no evidence of intracranial hemorrhage, mass or edema. 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.
