    • "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: Thoracic outlet syndrome (TOS) results from compression of the neurovascular structures that pass through the thoracic outlet. TOS may be classified as neurogenic TOS (NTOS), venous TOS (VTOS), or arterial TOS (ATOS). NTOS presents with upper-extremity symptoms attributable to compression of the brachial plexus. VTOS, also known as Paget-Schröetter Syndrome, involves subclavian-axillary venous occlusion, thrombus formation, and rare embolization. ATOS results from obstruction of the subclavian artery with claudication, thrombus formation, and possible embolization. Adjunct diagnostic studies frequently confirm the diagnoses of VTOS and ATOS, but not of NTOS. Successful TOS treatment depends on the establishment of an accurate diagnosis and identification of causative factors. NTOS should be treated initially with physical therapy, but may require surgical decompression, including first rib excision and scalenectomy. VTOS usually requires urgent thrombolysis, anticoagulation, and surgical decompression. The treatment of ATOS is directed at restoring arterial blood flow in addition to surgical decompression.
