Diagnosis With Brief Discussion

Diagnosis
Poland syndrome
Radiologic Findings
Chest radiograph shows slightly hyperlucent left lung (Fig. 1). CT scan demonstrates absence of the left pectoralis major and minor muscles (Fig. 2,3).
Brief Review
Poland syndrome is a rare congenital anomaly characterized by hypoplasia of the breast and nipple, scarcity of subcutaneous tissue, absence of the costosternal portion of the pectoralis major muscle, lack of the pectoralis minor muscle, aplasia or deformity of the costal cartilages or ribs II to IV or III to V, alopecia of the axillary and mammary region, and unilateral brachysyndactyly. The condition is more frequent among males, and usually occurs on the right hemithorax in the unilateral form.
. Chest radiography reveals an area of hyperlucency on the affected side that mimics a radical mastectomy or Swyer-James syndrome. CT more clearly depicts the absence of pectoralis major muscle and allows better appreciation of other associated musculoskeletal anomalies.
