The authors report a case of quadrilateral space syndrome in a baseball pitcher. The diagnosis was made by means of subclavian arteriography performed with the arm in abduction and external rotation. This entity is a rare cause of shoulder pain caused by occlusion of the posterior humeral circumflex artery in the quadrilateral space.
