Question: A 51-year-old woman underwent routine chest radiography. Posterior-anterior chest radiography showed a smooth, well-circumscribed soft tissue density mass in the right cardiophrenic angle that measured 5 cm in diameter and rendered the right cardiophrenic angle opaque (Figure A, arrow). The lateral view identified the anterior position of the mass (Figure B, arrow).
