Resumen

Los schwannomas del nervio glosofaríngeo son tumores de la fosa posterior extraordinariamente raros. En una revisión de 100 años se encontró un total de 42 casos entre 1908-2008. Los datos clínicos más comunes se encuentran asociados a su localización, siendo los más comunes síntomas vestíbulo cocleares y síntomas de afectación de la función del nervio glosofaríngeo. Su diagnóstico actualmente se ha facilitado con el uso de la resonancia magnética; sin embargo, es muy complicado definir en ocasiones preoperatoriamente si el tumor se origina del ix, x u xi nervios craneales. Presentamos el caso de una paciente de 42 años con síndrome del ángulo pontocerebeloso, síndrome del agujero rasgado posterior (yugular) + condileo anterior (Collet-Sicard). El tratamiento empleado fue quirúrgico con abordaje extremo lateral transcondilar, con monitorización de pares craneales y potenciales evocados transoperatorios.

Abstract

Schwannomas of the glossopharyngeal nerve are extremely rare tumors of the posterior fossa. In a 100-year review, a total of 42 cases were found between 1908-2008. The most common clinical data are associated with its location, the most common being cochlear vestibule symptoms and symptoms of glossopharyngeal nerve function. its diagnosis has now been facilitated by the use of magnetic resonance, however, it is very complicated to define preoperatively if the tumor originates from the ix, x or xi NC. We present the case of a 42-year-old patient with a syndrome of angulopentocerebellar syndrome, posterior torn (jugular) hole syndrome + anterior condyle (Collet-Sicard). The treatment used was surgical with transcondylar lateral extreme approach, with monitoring of cranial nerves and trans-operative evoked potentials.
