Isolated lateropulsion of the trunk in cerebellar infarct

MRI in a 63-year-old male with isolated lateropulsion of the trunk disclosed an infarct in the inferior portion of the right cerebellar hemisphere, suggesting an end-zone type infarct in the lateral branch of the right posterior inferior cerebellar artery (lPICA) or a borderzone infarct between lPICA and superior cerebellar artery. A close clinico-topographical relationship between isolated lateropulsion of the trunk and lesion in the territory of lPICA was demonstrated.
