A Report of a Case Involving Body Lateropulsion with Numbness of the Ipsilesional Fingers Caused by a Small Infarction in the Dorsal Part of the Middle Medulla

Abstract

Based on the complexity of functional anatomy, a small infarction in the medulla can produce various types of clinical symptoms or signs depending on the location of this infarction. We describe the case of a 46-year-old man who presented with sudden onset of body lateropulsion to the left side and numbness of the ipsilateral fingers. 3-tesla diffusion-weighted magnetic resonance imaging with a section thickness of 2 mm revealed a small infarction in the dorsal part of the left middle medulla. To our knowledge, this is the first case report describing vestibular dysfunction apparent upon otoelectrophysiological examination but without vestibular symptoms or signs except for body lateropulsion.
