A 51-year-old man with hypertension told his physician
that in the past five hours his right arm and leg and the right side of his
face felt weak. He had no sensory, cognitive, or language deficits, and an MRI
was performed. What does the MRI show?
The MRI shows an infarct (indicated by the arrow) in the internal capsule, resulting in the described motor deficits. Hypertension is a major risk factor for this type of stroke.
