Infra-clavicular approach to posterior cord brachial plexus schwannoma.

BACKGROUND: Brachial plexus schwannoma arising from the posterior cord is pretty rare. Approach to these tumors is not standardized. CASE DESCRIPTION: A young male presenting with pain radiating along the left shoulder and subtle weakness of left shoulder abduction had a moderate-sized mass located in the infraclavicular region. Excision of the lesion was planned through the infraclavicular approach. Division of the pectoralis minor was done with retraction of the pectoralis major. Complete excision was done along with the infraclavicular component. Postoperative outcome was good with complete return of functionality of the arm. Histopathologically, the lesion was a benign schwannoma. CONCLUSION: Posterior cord Brachial Plexus Tumours are uncommon but can be easily approached via the infra-clavicular route with good outcomes.
