Ten patients with SCA infarction who presented with cerebellar symptoms were studied by brain MRI,angiography,and underlying pathology.Brain MRI demonstrated an infarct in the SCA territory in the anterior rostral cerebellum of all patients.None had abnormalities in the brain stem.In four patients,a hemorrhagic infarct was present in the same region. Cerebral angiography revealed no obvious SCA occlusions or atherosclerotic vascular disease in any patient.Eight of the 10 patients had heart disease,such as atrial fibrillation or old myocardial infarction.The presumed diagnosis was occlusion of the SCA in its periphery due to cardiogenic embolism.When a patient presents with only cerebellar symptoms and has cerebellar infarction demonstrated by brain MRI,and SCA branch is probably occluded by cardiogenic embolism. |
