We report a duplicated right internal jugular vein found during a conservative neck dissection. The internal jugular vein is the largest vein in the neck and is an important anatomical landmark for neck dissections. It commences at the jugular foramen, continuing from the sigmoid sinus. It then runs a straight course through the carotid sheath, picking up multiple tributaries, and finally drains into the brachiocephalic vein. cephalic vein. It provides venous drainage for the brain, face, and neck.1,2
