During routine dissection of a middle-age male cadaver, an unusual course of the superior root of the ansa cervicalis was observed. In this case, the superior root of the ansa cervicalis fused with the vagus and ran within the carotid sheath, and then joined the inferior root forming the ansa cervicalis in the anterior wall of the carotid sheath. The study of this case will add to our current knowledge of ansa cervicalis and thus aid prevention of injury to the nerve during various surgical procedures. M3 ER -
