[Collet-Sicard Syndrome due to Occipital Condyle Fracture. Case Report].

The case of a 63-year-old man diagnosed with Collet-Sicard syndrome due to a fracture of the right occipital condyle is presented. The cause of injury was falling off a bicycle. Dysphonia and dysphagia were present from the moment of injury, with the gradual development of light atrophy of the tongue muscles and right trapezius muscle. The diagnosis was based on examination by CT and MRI methods, the act of swallowing and physical examination by an otorhinolaryngology specialist and a neurologist who confirmed the diagnosis of injury to cranial nerves IX, X and XI on the right side. The patient was treated conservatively with application of a Philadelphia collar. Dysphagia required PEG tube insertion. Skull fracture healing was evident on a CT scan at 3-month follow-up. However, dysphonia with dysphagia and muscle atrophy remained persistent.
