Abstract
- A cerebral infarction involving the nodulus usually produce contralateral lateropulsion and ipsilateral spontaneous nystagmus to the lesion. Here, we report a case of atypical isolated nodular infarction showed ipsilateral lateropulsion and contralateral spontaneous nystagmus to the lesion with a normal head impulse test. A right-handed 70-year-old man developed sudden vertigo with an unsteady gait. Neurologic examination revealed spontaneous left-beating nystagmus with a torsional component. He also displayed imbalance of walking and axial lateropulsion to the right side. Head impulse test was normal. Magnetic resonance imaging indicated acute infarction in the right nodulus on diffusion-weighted images.
