ABSTRACT
Body lateropulsion is a common manifestation of lateral medullary infarction (LMI), and usually associated with vertigo, limb ataxia, sensory disturbance, and Horner’s syndrome. However, isolated body lateropulsion as a presenting symptom of LMI is rare, and the responsible lesion for lateropulsion remains uncertain. We report a 71-year-old woman who showed isolated body lateropulsion as a presenting symptom of LMI. Ipsilateral body lateropulsion in our patient may be ascribed to the involvement of the ascending dorsal spinocerebellar tract rather than the descending lateral vestibulospinal tract, which runs more ventromedially.
Keywords: Body lateropulsion; Lateral medullary infarction; Dorsal spinocerebellar tract
