Subpulmonic effusion -Radiological sign

Radiological Signs (Erect Chest X-ray):

1.Pseudodiaphragm Appearance: The dome of the diaphragm appears elevated, often creating a smooth, "flatter" contour.

2.Lateral Diaphragmatic Peak: The peak of the diaphragm is displaced laterally rather than being in the middle, creating a "hump".

3.Increased Left Lung-Gastric Bubble Distance: On the left side, the distance between the lung base and the stomach bubble (air-fluid interface) is increased, usually > 2cm
