There are multiple, bilateral, rounded soft tissue density masses on the chest x-ray. There are also moderate sized bilateral pleural effusions, but the mediastinum looks normal, and there are no obvious bony lesions.

This shows a large right sided renal mass, later confirmed to be a renal cell carcinoma.
