Morphological variations of the brachial plexus and variants in the distribution of the anterior division of the middle trunk are relatively frequent. Two of the rarest anomalies occurred in the left brachial plexus of a 62-y-old Japanese male, 1 of 104 plexuses dissected between 1996 and 1997 at Kanazawa University Faculty of Medicine. The superior trunk of the brachial plexus was formed by the anterior primary division of C5 and C6 and a thin branch (0.5 mm in diameter) from C4, the middle trunk by the C7, and the inferior trunk by C8 and T1 (Fig.). We could not determine whether there was a branch derived from T2 to T1, since the subject had died of lung carcinoma. The entire anterior division of the middle trunk crossed the axillary artery and joined the medial root of the median nerve which was the continuation of the medial cord after the cord branched off the ulnar nerve. The lateral cord pierced coracobrachialis and divided into the musculocutaneous nerve and the lateral root of the median nerve just after emerging from the muscle, finally joining the medial root of the median nerve superficial to the brachial artery [similar]115 mm distal to the lower border of latissimus dorsi to form the median nerve. The musculocutaneous nerve gave rise to the nerves to biceps brachii, brachialis, and the long head of biceps brachii and finally continued as the lateral cutaneous nerve of the forearm. The branch to coracobrachialis had already been cut and its course could not be traced.
