Unilateral neurovascular and muscular variations in the right upper limb

In the present case we observed a right upper limb with various variations, those includes variation in branching pattern of axillary artery, third head of biceps brachii, double brachial artery and insertion of biceps brachii forming a tunnel for both the brachial arteries and median nerve. Such attachment of biceps brachii may compress the structures beneath it and lead to neurovasculopathy. The variation in the present case was compared with those reported before. All the above-mentioned variations were observed unilaterally in male embalmed cadaver. As per our knowledge all these variations have observed by many authors; however, in our case we observed them together in a single limb. So, it may be important to know for vascular surgeons, radiologists, surgeons and clinical anatomists.
