MR and CT in the Assessment of Poland Syndrome

Abstract

Seven cases of Poland syndrome were investigated with CT and/or MR to assess the extent of the muscle abnormalities of the shoulder girdle. In all cases the absence of the sternocostal head of the pectoralis major was clearly shown, as were any associated abnormalities of the pectoralis minor, serratus anterior, and latissimus dorsi. The latissimus dorsi muscle has an important role in reconstructive surgery and can be difficult to assess clinically. Cross-sectional imaging with CT or MR will give useful information in patients with Poland syndrome requesting anterior axillary reconstruction and breast mound formation.
