Clinical presentation is typically lacunar, e.g., pure motor hemiparesis of face, or of the arm and leg. Alternatively, clinical presentation is other than the classically described lacunar stroke, but brain image report demonstrates deep infarct < 1.5 cm that could explain the clinical syndrome. |
