| Summary: | Introduction: Variations to the course of carotid arteries may lead to abnormal pharyngeal protrusions, to which the otorhinolaryngologist should always attentive. Objective: To report a case of abnormal pharyngeal protrusion due to vascular anomaly in the course of the internal carotid artery, with literature review. Case Report: A 73- year-old woman complained of globus pharyngeus and intermittent dysphonia. A pulsating convexity was observed at the right part of the oropharynx, associated to laryngoscopic signals of pharyngo-laryngeal reflux. The pharyngeal computed tomography scan showed an abnormal tortuous internal carotid in the retropharyngeal space. The patient was sent to the vascular surgeon, who, after a normal blood flow finding at the Doppler, opted for an expectation conduct. The pharyngeal symptoms improved with the antireflux treatment. Final Comments: Internal carotid vascular anomalies must always be recalled in the pharyngeal wall convexity differential diagnosis. |
