Computed Tomography of the Pectoralis Muscles in Poland's Syndrome.

Abstract

Computed tomography (CT) can demonstrate disorders of the chest wall muscles clearly. CT scans of the thorax were carried out in seven patients with Poland's Syndrome. All patients with Poland's Syndrome had the clavicular portion of the pectoralis major, but were lacking the sternocostal portion of the pectoralis major. The pectoralis minor was absent in four of seven patients.
