title: The quadrilateral space syndrome.
abstract: We describe a 21-year-old woman with left shoulder pain increased by desk work. Left subclavian angiography disclosed occlusion of the posterior circumflex humeral artery on abduction and external rotation of the arm, compatible with the previous reports of the quadrilateral space syndrome. This syndrome should be considered in patients with shoulder pain of unknown aetiology.
