Abstract

The current case report describes an uncommon insertion of the levator scapulae (LS), which broadly attaches to multiple structures, including the serratus posterior superior, ligamentum nuchae, and the 6th and 7th spinous processes of the cervical vertebrae. The most superior portion of this aponeurosis merged with the ligamentum nuchae at the C7 level. The middle and inferior portions of the head were inserted (or fused) into the tendon of the rhomboid minor as well as the fibers of the serratus posterior superior muscle. Consequently, recognizing this anatomical variation, characterized by an additional slip of the LS attaching to the 7th vertebra and other muscular structures, is crucial not only for anatomists but also for surgeons performing procedures on the posterior neck related to cervical or shoulder pain and cervical dystonia.
