Levator scapulae muscle

The levator scapulae is a strap-like, deep posterior neck muscle that extends from the transverse processes of the upper cervical vertebrae (C1–C4) to the superior angle and medial border of the scapula. It lies deep to the trapezius and superficial to the cervical transverse processes, running obliquely downward and laterally. The muscle is closely associated with the splenius cervicis, rhomboid minor, and the accessory nerve, and is enveloped by deep cervical fascia.

The levator scapulae is important for elevating the scapula, assisting in downward rotation, and stabilizing the scapula during arm movement. It also contributes to cervical spine lateral flexion when the scapula is fixed. Its clinical significance includes tension-related neck pain, scapular dyskinesis, and entrapment neuropathies involving the dorsal scapular nerve.

Function

  • Elevates the scapula

  • Assists in downward rotation of the scapula

  • Stabilizes the scapula during upper limb movement

  • Contributes to lateral flexion of the neck

  • Plays a role in posture and shoulder girdle mechanics

Synonyms

  • Levator scapulae

  • Muscle elevating scapula

  • Cervical scapular elevator

MRI Appearance

T1-weighted images:

  • The levator scapulae appears as an intermediate signal intensity muscle located posterolaterally in the neck

  • Muscle fibers run obliquely from cervical transverse processes to the scapula

  • Surrounded by hyperintense fat planes, which enhance contrast and help differentiate from adjacent muscles

T2-weighted images:

  • Normal muscle is intermediate signal intensity

  • Edema, strain, or inflammation appears hyperintense

  • T2 imaging helps detect muscle tears, myositis, or traumatic injury

STIR (Short Tau Inversion Recovery):

  • Muscle is intermediate signal, while pathological edema or inflammation appears bright (hyperintense)

  • Highly sensitive for detecting acute injury or inflammatory conditions

T1 Post-Contrast (Gadolinium-enhanced):

  • Normal levator scapulae shows minimal to no enhancement

  • Pathological conditions such as myositis, infection, or tumor demonstrate focal or diffuse enhancement

CT Appearance:

  • Muscle appears as a soft tissue density structure extending from cervical transverse processes to the superior scapular angle

  • Fat planes around the muscle are hypodense, providing natural contrast

  • CT is useful for evaluating muscle bulk, calcifications, masses, or adjacent bony anatomy
