Introduction: The musculocutaneous nerve is one of the branches from the lateral cord of brachial plexus. This nerve is solely devoted to the flexor compartment of arm hence it is called as nerve of arm. Numerous studies have been reported about the variations of this nerve but the real prevalence is still unknown, whereas, it may be hypothetical.

Case report: This study shows a rare branching pattern where a thin nerve takes origin from the medial fasciculus of brachial plexus which then pierces the coracobrachialis and lies between the biceps brachii and brachialis. The nerve then pierces the biceps to supply the skin over the lateral surface of forearm. The median nerve took over the muscular branches of musculocutaneous nerve by giving off the branches to both biceps and brachialis.
