During routine dissection of an adult male cadaver, we observed bilateral communication between musculocutaneous nerve and median nerve. The level of origin of the communicating branch from musculocutaneous nerve was different in both arms. In left arm it arose before piercing coracobrachialis and in the right arm after piercing it. It is important to be aware of this variation while planning a surgery in the region of arm, as these nerves are more liable to be injured during operations. Any compression over the communicating branch may give rise to varying patterns of weakness that may impose difficulty in diagnosis for the neurologists.
