The brachial plexus is an anatomically complex structure. Tumors that originate from the brachial plexus are rare and present clinical challenge for neurosurgeons due to the anatomical complexity. We present the case of 59-year-old male patient with right hand weakness who was diagnosed with a neurogenic tumor originating from brachial plexus. He underwent wide the excision of tumor through the anterior supraclavicular approach. Postoperatively, the patient developed right arm numbness and motor weakness. At 2 month following the removal of tumor, he recovered normal function.
