During routine dissection of a 25-year-old male cadaver, we observed C5 and C6 nerve roots pierced anterior scalene muscle bilaterally and then formed the superior trunk of brachial plexus after merging on the anterolateral aspect of the muscle. Suprascapular nerve originated from the superior trunk bilaterally. Knowledge of such variations may be important in the diagnosis of upper limb paresthesias.
