This document reports on an anatomical variation found during a dissection of a male cadaver. Specifically, it describes the fusion of the lateral cord of the brachial plexus with the median nerve, and the absence of the musculocutaneous nerve, in the right upper limb. Normally the lateral cord would branch into the musculocutaneous nerve and lateral root of the median nerve. Here, the lateral cord fused with the median nerve proximal to the coracobrachialis muscle insertion. As a result, branches that would normally come from the musculocutaneous nerve instead originated from the median nerve. The cause of this variation may be related to errors in embryonic development of the nerves. Knowledge of such
