Case 9
This radiograph demonstrates a paramedian mass in the right lung apex, colloquially referred to as a Pancoast tumor. The lateral margin of the mass is visible above the clavicle, which localizes the mass to the posterior mediastinum (negative cervicothoracic sign). The patient is slightly rotated to the left. Multiple chronic bilateral rib fractures are present. A nipple ring projects over the left chest wall.
