Abstract
Lateral medullary infarction (LMI), or Wallenberg syndrome, can develop various symptoms, but it is rare that ipsilateral axial lateropulsion (or body lateropulsion, BL) or atonic bladder (AB) are caused by LMI. This report describes a case of LMI with both BL and AB. A 77-year-old man, with a history of hypertension and diabetes, developed acute left BL and anuresis. A neurological exam showed right gaze nystagmus, slight dysarthria and dysphagia, right dysesthesia in the trunk, and ataxia in the left limbs and trunk. Horner's syndrome and paralysis were unremarkable. Brain magnetic resonance imaging revealed hyperintensity in the lateral medulla oblongata. Cystometry revealed AB, although the patient had the urge to urinate. Owing to acute therapy, although trunk ataxia was presented for several months, BL and anuresis were recovered on day 15 and day 35, respectively. Here, we describe the potential mechanisms of BL and AB caused by LMI.
