title: Opalski's Syndrome with Cerebellar Infarction.
abstract: A 64-year-old man presented with sudden onset of right-sided hemiparesis, headache, gait disturbance, and recurrent vomiting. A physical examination revealed right-sided hemiparesis, right Horner syndrome, ataxia of the right limbs, and diminished sensation on the left side of his body. Diffusion-weighted MRI revealed an acute right lateral medullary infarction extending from the rostral medulla to the upper cervical cord, and an acute cerebellar infarction in the territory of the medial branch of the posterior inferior cerebellar artery. Magnetic resonance angiography revealed suspicious severe stenosis or near occlusion of the proximal and distal parts of the right vertebral artery, and hypoplasia of the left vertebral artery. We diagnosed ipsilateral hemiparesis with lateral medullary infarction (Opalski's syndrome) and concomitant cerebellar infarction.
