A Unique Anatomical Variant of the Levator Scapulae Muscle: A Case Report

Musculature variations in the head and neck are typically observed in cadaveric dissections. Some of these variations could involve the levator scapulae muscle, which may lead to cervical and postural misalignment. The levator scapulae function to elevate the scapula and rotate it downward. In this case report, we present an 88-year-old male cadaver diagnosed with thoracic kyphosis having a double-bellied levator scapulae, originating from the transverse processes of C1-C4 and the mastoid process. This abnormality, not found elsewhere in our search of literature, can give physicians insight into upper back pain management and surgical navigation of the posterior cervical and upper back regions.
