Discussion
This radiograph demonstrates a lobulated mass in the left perihilar region. Also of note is the presence of a unilateral implant in the left breast, suggesting a history of mastectomy and breast reconstruction. Together these findings are highly suggestive of pulmonary metastatic disease from breast cancer. However, tissue diagnosis would be required for confirmation as a primary lung malignancy and metastatic disease from a different, unknown primary are also possible.
The exam is otherwise unremarkable.
