Left arm weakness and dizziness, evaluate for ischemia No diffusion restriction is seen to suggest acute ischemia. Increased FLAIR signal in the periventricular white matter and small foci in the subcortical white matter is compatible with mild small vessel ischemic disease. The CSF spaces are appropriate for the patient's stated age. The brain parenchyma is otherwise normal in signal intensity without mass or mass effect. Extracranial soft tissues are grossly unremarkable.
MRI with limited sequences demonstrates no evidence of acute infarct. No intracranial mass or mass effect. Mild chronic small vessel ischemic disease again seen.
