Collet-Sicard syndrome is a unique condition involving lesions of the skull base, which affect both the jugular foramen and the hypoglossal canal, affecting the lower cranial nerves IX, X, XI and XII. Symptoms of this pathology include loss of taste in the posterior third of the tongue (IX nerve), vocal cord paralysis and dysphagia (X nerve), weakness in the sternocleidomastoid and trapezius (XI nerve) muscles and atrophy and paresis of the tongue muscles (XII nerve). The present report aims to describe the case in question, referring to a syndrome rare and little described in the literature. In the case of the patient reported, the conduct adopted was to perform radiotherapy sessions in order to prevent tumour progression since the surgery was contraindicated.
