Head and Neck ImagingLevator claviculae muscle
normal anatomical variant, occurring in 2 - 3% of the population. It should be distinguished from an abnormality on cross-sectional imaging, particularly
lymphadenopathy head and neck. This muscle has its origin in the upper part of the
cervical spine and inserts into the middle or lateral third of the clavicle. Rarely, the muscle itself causes clinically the impression of a posterior neck mass
lesion (
Fig.1).
