75-year-old female with drop attacks, subsequent nausea; rule out posterior circulation hemorrhage, TIA There are increasing periventricular and subcortical hypoattenuating lesions which is nonspecific but may represent increased small vessel disease of indeterminate age. Recommend MRI if high clinical concern for ischemic CVA. Again seen is an evolving right basal ganglia lacunar infarct. There is no evidence of intracranial hemorrhage, mass or edema. The ventricles and sulci are prominent which is consistent with mild parenchymal volume loss. The calvaria and skull base are radiographically normal. The visualized paranasal sinuses and mastoid air cells are normally pneumatized.
Increased small vessel disease of indeterminate age. No evidence of acute intracranial hemorrhage. Recommend MRI if high clinical concern for ischemic CVA.Mild parenchymal volume loss and evolving lacunar infarct as described above.
