During a routine
dissection of the right upper limb of a 65-year-old male cadaver whose death is not clear, we found
two anatomical abnormalities on the musculocutaneous nerve and brachial artery
on the same arm. First, the musculocutaneous nerve derived from the lateral fascicles of brachial
plexus by two branches. Second, the brachial artery emitted the radial and
ulnar arteries at the level of 1/3 proximal upper arm. Given these variations
are discovered rarely and accurate knowledge of such variations is important
for both surgeons and radiologists.
