ABSTRACT
El síndrome de Villaret se define por la afección de los nervios craneales glosofaríngeo (IX), vago (X), espinal (XI) e hipogloso mayor (XII), en conjunción con el síndrome de Horner homolateral a la lesión. Se produce por compresión de estos nervios y de las fibras vecinas del plexo simpático pericarotídeo en la base del cráneo, en particular, en el espacio retroparotídeo. Si bien es un hecho conocido la invasión del sistema nervioso central en el cáncer de pulmón avanzado, esta particular asociación sintomática es extremadamente infrecuente. Presentamos una paciente con diagnóstico reciente de adenocarcinoma de pulmón que desarrolló, en forma simultánea, este síndrome.
Villaret syndrome is defined by the affection of the glossopharyngeal (IX), vagal (X), accessory (XI) and hypoglossal (XII) cranial nerves associated with ipsilateral Horner syndrome. It is caused by the compression of these nerves and the neighboring sympathetic plexus fibers at the base of the skull, particularly in the retroparotid space. Even though the invasion of the central nervous system in patients with advanced lung cancer is a frequent and well known occurrence, this particular symptomatic association is extremely rare. We are reporting the case of a newly diagnosed lung adenocarcinoma patient who is simultaneously developing this syndrome.

A partir do relato de um caso sobre a síndrome de Villaret, o autor ressalta a importância da relação anátomo-clínica, aspectos clínicos e etiologias das síndromes que cursam com o comprometimento dos quatro últimos nervos cranianos quando da sua passagem extracranial.
From the case study of a patient with the Villaret syndrome the author emphasizes the importance of the anatomical-clinical relationship, clinical aspects, and etiologies of syndromes that are associated with the impairment of the last four cranial nerves during its out of skull passage.
