[Aberrant internal carotid artery: a rare cause of cough: about a clinical case]. / Artère carotide interne aberrante: une rare cause de toux (à propos d'un cas clinique).

Aberrant course of the internal carotid artery is a rare congenital malformation. Aberrant course of cervical internal carotid artery accounts for 5% of cases. Several cases of fatal hemorrhage due to an injury to the aberrant internal carotid artery have been observed in patients undergoing pharyngeal surgery procedures. This was associated with a lack of detection during surgery. Ear nose and throat (ENT) practitioner need to know it. We here report a case of aberrant internal carotid manifesting as chronic cough due to the contact of the epiglottis with the pharyngeal mass caused by the aberrant artery. The patient was treated for chronic lung disease without success. This particular anatomical condition should be suspected in patients with pharyngeal mass before any invasive procedure.
