Abstract:
Vascular variations in the neck region are not uncommon. Knowledge of incidence of morphological variations in
the course and branching of the carotid arteries is important for radiological interpretation and surgical correction
when they are symptomatic. Internal carotid artery (ICA) is known to show elongation in its extra cranial course.
Previous studies have demonstrated the incidence and clinical symptoms of this morphological entity. However, the
occurrence of elongation and looping of the external carotid artery (ECA) is seldom reported in the literature. During
regular dissections, we came across a rare case of unilateral morphological variation of both ECA and ICA, in a male
cadaver aged about 55 years. ICA presented a curved course with convexity directed posteriorly, at the level of the
C2-C3 vertebrae. ECA presented a pronounced kinking or coiling, one inch below the level of the angle of the
mandible. In addition, a linguo-facial trunk arising from the ECA also presented a pronounced kinking throughout its
entire length.
