Abstract

Objective:

We describe a case of an internal carotid artery loop presenting as an oropharyngeal mass.

Method:

Case report and review of current literature.

Case report:

A 71-year-old woman presented with an asymptomatic oropharyngeal mass. This was an incidental finding by her general practitioner and was urgently referred as a suspicious lesion. A magnetic resonance imaging scan revealed an internal carotid artery tonsillar kink indenting into the pharyngeal wall. No further treatment was necessary.

Conclusion:

The internal carotid kink is an important anatomical variation which ENT surgeons should be aware of, as there are significant complications if blind biopsy is undertaken prior to appropriate imaging.
