A Rare Case of Stroke in an Adolescent Violinist Due to Thoracic Outlet Syndrome.

Thoracic outlet syndrome (TOS), a rare condition, results from the compression of neurovascular structures traversing from the neck through the thoracic outlet into the axilla. It can develop from chronic repetitive activities of the upper extremities, commonly reported in athletes playing sports involving vigorous use of arms and shoulders. While symptoms of neurovascular compression can occur, stroke due to TOS in children is not commonly reported. We describe a rare case of a healthy 14-year-old boy, a competitive violinist, with acute limb ischemia from extensive occlusive thrombi involving several arteries in the right upper extremity as well as the right vertebral artery, which ultimately caused infarcts in the bilateral posterior circulation. The etiology was determined to be TOS leading to impingement of the right subclavian artery by a fused cervical rib aggravated by patient's prolonged violin practice. This case represents the first description of stroke from TOS in an adolescent violinist.
