CTICasesPoland syndrome
Imaging findings
Chest radiograph shows asymmetry in soft tissue density between the two hemithoraces, with a hyperlucent right lung field. 3D skin and muscle reconstructions demonstrate complete absence of the right pectoralis major muscle, with normal pectoral musculature on the left, and a cleft between the arm and chest wall extending deep into the axilla.
Key takeaways
Poland syndrome is a rare congenital anomaly characterized by unilateral chest wall hypoplasia or aplasia, most commonly affecting the pectoralis major muscle, and variable ipsilateral upper limb anomalies. On a chest radiograph, it causes unilateral hyperlucency that can be mistaken for a parenchymal or airway process.
