Abstract
BACKGROUND: Lacunar infarcts are small, deep cerebral infarcts resulting from occlusion of small, penetrating cerebral arteries. They are most commonly associated with hypertension. Cardiac sources of embolization are sometimes present in patients with lacunes, but direct proof of a causal relationship is lacking. This report attempts to support the contention that emboli can cause lacunar syndromes and lacunar infarction. CASE DESCRIPTIONS: We report two cases of pure motor hemiplegia, each of which developed while the patient was undergoing cardiac or aortic arch angiography. Neither patient had a history of previous transient ischemic attack or stroke. Initial computed tomography of the brain was normal in each. Repeat computed tomography in one confirmed a small, low-density lesion in the posterior limb of the internal capsule on the side appropriate to the patient's symptoms and remained normal in the second patient. CONCLUSIONS: These two cases offer evidence that the classic lacunar stroke syndrome of pure motor hemiplegia can occur on an embolic basis.
