An Unusual Observation During Neck Dissection.

External jugular vein (EJV) is a major superficial vein in the neck which drains deeper parts of face and posterior scalp region. Although it follows a predicted pattern in formation, course and termination in general unusually it also exhibits variations which are clinically important. Gross variations in the incidence of these variations in EJV are noted. We report an anomalous course of EJV which drains into internal jugular vein in our case report. Knowledge about EJV and its origin, course and termination is important for surgeons, interventional radiologist, anaesthesiologist, clinicians in general to avoid inadvertent complication.
