Diagnostic imaging approach of the patient. A Posteroanterior chest radiograph showing a radiopaque image dependent on the right costal grid, corresponding to the tumor, with areas of radiopacity in the right lung that do not obscure the cardiac silhouette anterior to the heart. B Image of the patient with increased volume in the anterior and lateral right chest. C Chest and abdomen computed tomography, axial views at the level of the largest tumor extension. A heterogeneous solid lesion with central calcification originating from the anterolateral costal arches of the 3rd to 5th ribs is observed, expansively extending into the lung parenchyma, involving the entire extent of the thoracic wall from the inside to the outside, causing loss of normal anatomy and function.
