Abstract
The bilateral absence of the ansa cervicalis was discovered during dissection of the neck in an elderly male cadaver. On both sides it was replaced by a vagocervical plexus formed by the vagus nerve and C1 and C2 ventral rami from the cervical plexus. A descending branch from this vagocervical plexus supplied the strap muscles of the neck. From a review of the literature the incidence of bilateral absence of the ansa cervicalis and its replacement by a vagocervical plexus appears to be extremely rare. Morphological variability, embryological basis, and clinical relevance of this uncommon anatomical variant are discussed.
