Overview
Chest films acquired in the lateral decubitus position (with the patient lying on their side) are more sensitive, and can detect as little as 50 ml of fluid. At least 200ml-300 ml of fluid must be present before upright chest films can detect signs of pleural effusion (e.g. blunted costophrenic angles).[1]
Chest X Ray
-
Pleural effusion Chest x-ray of a pleural effusion. The arrow A shows fluid layering in the right pleural cavity. The B arrow shows the normal width of the lung in the cavity
-
Large unilateral right sided effusion. Heart is enlarged, especially the left lateral appendage.
-
Right side pleural effusion. A homogenous opacification is noted in the right lower zone. The right costophrenic angle is obliterated with a meniscus noted.
-
Small bilateral pleural effusions that layer with decubitus views
