Accidental and potentially life-threatening finding: pulsatile mass of the hypopharynx

Anatomical variations of the cervical part of the internal carotid artery (ICA) are not rare in the general population. They are usually asymptomatic and more common in the elderly. We report the case of a 70-year-old Caucasian woman who was referred to our department due to chronic cough. We performed a flexible nasofibrolaryngoscopy that demonstrated the presence of a pulsatile mass in the hypopharynx. After performing a cervical contrast-enhanced CT, the mass turned out to be an aberrant variation of the cervical part of the ICA. This case is intended to alert otolaryngologists, anaesthesiologists, radiologists and surgeons for this accidental finding and the possible consequences for the patient if not diagnosed and properly oriented.
