Abstract

We report an atypical Wallenberg syndrome presented with an acute vertigo, preceded by headache, simulating a peripheral vestibular pathology. The first magnetic resonance imaging (MRI) study done in urgencies is negative. Presence of headache, strong lateral ataxia and secondary focally neurological symptoms 48 h after the beginning of the crises, lead to a repetition of the MRI which shows a right lateral bulbar infarct. We focus on the semiological elements that can guide us to a lateral bulbar pathology in patients with pseudoperypheric symptoms (axial lateropulsion, ocular laterodeviation, posterior headache, oculographic test, etc.).

Keywords:
Headache
Ataxia
Lateral bulbar pathology
Resumen

Se presenta un síndrome de Wallenberg atípico que se manifiesta con un vértigo agudo aislado, precedido de cefalea, que simula una afectación vestibular periférica. La primera Resonancia Magnética Nuclear (RMN) realizada de urgencia es negativa. La presencia de la cefalea, la fuerte ataxia lateral y la aparición secundaria de signos neurológicos focales a las 48h del comienzo de la crisis llevan a realizar una nueva RMN que muestra un infarto bulbar lateral derecho. Se llama la atención sobre los elementos de la semiología que pueden orientar hacia una lesión bulbar lateral ante la presencia de un cuadro clínico pseudoperiférico (lateropulsión axial, laterodesviación ocular, cefaleas posteriores, examen oculográfico, etc.).

Palabras clave:
