A variation of Musculocutaneous nerve without piercing the coracobrachialis muscle while communicate to the median nerve: A case report and literature review

CONCLUSION Anatomically, in the axilla region, the Musculocutaneous nerve is originated of the lateral cord of brachial plexus, then, by piercing the coracobrachialis muscle arrives enters to anterior compartment of the arm. But, in the present report, we observed that the Musculocutaneous nerve without piercing the coracobrachialis muscle arrive to the arm, then communicate to the Median nerve. To exploratory interventions of the arm for peripheral nerve repair and surgical therapies, a good knowledge of nerve pathways helps to surgeons for preventing possible mistakes during surgery.
