    • "In the clinic, the levator claviculae has the potential to be misidentified as a cyst, an arterial aneurysm, a neurofibroma , metastasis, a lymphadenopathy (Rüdisüli 1995; Rosenheimer et al. 2000), the sternocleidomastoid (Feigl and Pixner 2011), or a thrombosed vein (Rubinstein et al. 1999) in imaging diagnostics. From another standpoint, the levator claviculae has the potential to cause thoracic outlet syndrome, a rare condition that involves compression at the superior thoracic outlet, leading to pain, arm discoloration, and tingling, among other symptoms (Aydog ˘ et al. 2007). As such, it is important for surgeons and radiologists to be aware of this variation (O'Sullivan and Kay 1998; Ruiz Santiago et al. 2001; Shaw and Connor 2004). "

    ABSTRACT: We report here an anatomical study of the levator claviculae discovered during an anatomical dissection course for medical students. The muscle was identified on the left side, and followed a typical topography to previous detections, originating from the transverse process of the fourth cervical vertebra and attaching to the upper facet of the middle part of the clavicle. Innervation to this muscle came from both the third and fourth rami of the cervical spinal nerves. Blood supply to the muscle could not be identified clearly. In this report, we undertook a comprehensive literature survey of this muscle dating back ca. 170 years, and attempted to ascertain the phylogenic and ontogenetic explanations for the development of this muscle.

    ABSTRACT: In the current study a levator claviculae muscle, found in a 65-year old male cadaver, is presented. We describe the topography and morphology of this accessory muscle, which may be found in 1-3% of the population. Moreover, we discuss the embryologic origin of the muscle along with its clinical importance.

    ABSTRACT: Reported here is a 30-year-old man who was seen because of pain and weakness in the upper extremities after a tractional injury. Physical examination revealed significant atrophy in the left deltoid and right intrinsic hand muscles, generalized hypoesthesia, decreased deep tendon reflexes bilaterally, and decreased strength in various muscle groups. Roos (right) and hyperabduction (bilateral) tests were positive. Electrodiagnostic studies were consistent with bilateral brachial plexopathy. Cervical radiographs showed long transverse process of C7 on the right side and a small rudimentary rib articulating with C7 on the left side. Brachial plexus magnetic resonance imaging demonstrated an aberrant muscle and compressive brachial plexus injury on the left side. Surgery via transaxillary approach was performed on the left side. The occurrence of traumatic brachial plexopathy in the presence of underlying thoracic outlet syndrome and subclavius posticus muscle is discussed for the first time in the literature.
