Pleural effusion, subpulmonic

Follow-up radiograph


In this patient there is an obvious right upper lung field opacification which on later work-up was determined to be a primary cancer. Note that the right lower lung field is clear and that the right diaphragm and lateral costophrenic angle seem sharp though it would seem peculiar that the right diaphragm should seem so high. Although pleural effusions are usually expected to blunt the costophrenic angle, occasionally a "subpulmonic" effusion may mimic the surface of the diaphragm which is the case here. When the decubitus film is obtained note the substantial amount of fluid that layers out.
