Background: A rare case of bilateral multiple anatomical variations in the upper extremity, was found in a male cadaver, during routine dissection in the Anatomy department at TN Medical College, Mumbai.
Observation: The variations included absence of Musculocutaneous nerve of right arm and communication of Musculocutaneous nerve with median nerve in the left arm, bilateral three heads of Biceps Brachii muscle and bilateral multiple tendons of Abductor Pollicis Longus muscle in both the arms.
Conclusion: Medical significance of an absent Musculocutaneous nerve and the presence of three heads of Biceps Brachii lies in the fact that it can cause traumatic nerve compressions or complications in anaesthetic block etc. Anatomic variations of tendons of abductor pollicis longus are significant in assessment of hand injuries and surgeons performing hand reconstructive surgery.
