Clinical question: Presence of intracranial abnormality. Signs and symptoms:somnolent, change in mental status. Unenhanced head CT:Nonspecific periventricular and subcortical foci of low-attenuation is highly suspected of small vessel ischemic disease of indeterminate age. Prior MRI also reveals presence of small muscle ischemic strokes.No evidence of acute intracranial hemorrhage, edema, mass-effect, midline shift or hydrocephalus.CT is insensitive for detection of early acute ischemic strokes.
