  • Title: Thoracic outlet syndrome in a patient with absent scalenus anterior muscle.
    Author: Collins RM, Bhana J, Patricios JS, Du Plessis A, Veller M, Schultz D, van Rensburg DC.
    Journal: Clin J Sport Med; 2014 May; 24(3):268-70. PubMed ID: 24451700.
    Abstract:
    This case report describes the rare anomaly of an absent right anterior scalene muscle presenting with the symptoms and signs of the thoracic outlet syndrome. The thoracic outlet syndrome in our patient can be attributed to the absence of the right anterior scalene muscle, which resulted in the brachial plexus being in proximity to the subclavian vein and artery in a narrowed and abnormal interscalene space. In addition, the absence of the anterior scalene muscle resulted in the neurovascular structures being compressed onto the first rib in the costoclavicular space. The most likely cause of the presentation is, however, the possibility of the presence of aberrant muscle slips, which would cause compression of the structures in the anterior (venous) and posterior (neurological) sections of the thoracic outlet.
