A case of traumatic vertebral artery pseudoaneurysm in a 16-year-old Nigerian male following a stab wound is described. Successful surgical treatment by proximal Subclavian artery control and excision of the lesion was achieved. The value of Doppler ultrasonography in the diagnosis is highlighted. This case illustrates and re-emphasises that this rare lesion should be considered in patients with neck mass following penetrating posteriorly located neck injuries.
