Anomalies of the brachial plexus and its terminal branches are not uncommon. Communicating branch arising from the musculocutaneous nerve to the median nerve is a frequent variation, whereas the presence of an anastomotic branch arising from the median nerve and joining the musculocutaneous nerve is very rare. During routine dissection of cadaver upper limbs, we observed an anastomotic branch arising from the median nerve running distally to join with the branches of the musculocutaneous nerve in a left upper extremity. The anastomotic branch originated from the median nerve 11.23 cm proximal to the interepicondylar line. After running distally and coursing between the biceps brachii and the brachialis muscles, this anastomotic branch communicated with two branches of the musculocutaneous nerve separately. The presence of the communicating branches between these nerves should be considered during surgical interventions and clinical investigations of the arm.
