84 year old female with mental status changes status post fall. Rule out subdural hematoma. There is no evidence of intracranial hemorrhage, mass or edema. Low-attenuation in the periventricular white matter is consistent with small vessel ischemic disease of indeterminant age. The ventricles and basal cisterns are normal in size and configuration.In the brainstem, there is a tortuous basilar artery partially obscuring the brainstem. This finding is unchanged. If there is a clinical suspicion of stroke, MRI may be considered.The calvaria and skull base are radiographically normal. The visualized paranasal sinuses and mastoid air cells are normally pneumatized.
1. No evidence of acute intracranial abnormality.2. Moderate small vessel ischemic disease of indeterminant age, unchanged.3. Unchanged tortuous basilar artery partially obscuring the brainstem. If there is a clinical suspicion of stroke, MRI may be considered.
