Unusual Branching Pattern of the Lateral Cord of the Brachial Plexus Associated with Neurovascular Compression Case report
Journal Title: Sultan Qaboos University Medical Journal - Year 2017, Vol 17, Issue 1
Abstract
Te brachial plexus consists of a network of nerves that innervates the upper limbs and its musculature. We report a rare formation of the lateral cord of the brachial plexus observed during the dissection of a 47-year-old male cadaver at the Department of Anatomy, Vardhman Mahavir Medical College, New Delhi, India, in 2016. Te lateral cord was exceptionally long with twin lateral pectoral nerves and twin lateral roots of the median nerve. Te proximal lateral root of the median nerve was thin in comparison to the medial root of the median nerve. Te distal lateral root of the median nerve was thicker and followed an unusual course through the coracobrachialis muscle. In the lower third of the arm, the median nerve and the brachial artery—along with its vena comitans—spanned through the brachialis muscle. Surgeons, anaesthesiologists, radiologists and anatomists should be aware of such anatomical variations as they may result in neurovascular compression.
