The costodiaphragmatic recess (or phrenicocostal sinus^[1]) is a potential space in the pleural cavity, at the posteriormost tips of the cavity, located at the junction of the costal pleura and diaphragmatic pleura. It measures approximately 5 cm vertically, and extends from the eighth to the tenth rib along the mid-axillary line.

Function

The lungs expand into this recess during forced inspiration, however the recess never fills completely. During expiration, it contains no lung tissue, only pleural fluid.

Clinical significance

Pleural effusions collect in the costodiaphragmatic recess when in standing position.^[2]

A thoracocentesis (pleural tap) is often performed here while a patient is in full expiration because of less risk of puncturing the lungs and thereby causing pneumothorax.^[2]

Imaging

Comparison between a normal costophrenic angle on the patient's right, and an obscured costophrenic angle (circled) on the patient's left, due to pneumonia with parapneumonic effusion.

In anatomy, the costophrenic angles are the places where the diaphragm (-phrenic) meets the ribs (costo-).

Each costophrenic angle can normally be seen as on chest x-ray as a sharply-pointed, downward indentation (dark) between each hemi-diaphragm (white) and the adjacent chest wall (white). A small portion of each lung normally reaches into the costophrenic angle. The normal angle usually measures thirty degrees.

Pleural effusion

With pleural effusion, fluid often builds up in the costophrenic angle (due to gravity). This can push the lung upwards, resulting in "blunting" of the costophrenic angle. The posterior angle is the deepest. Obtuse angulation is sign of disease.

Chest x-ray is the first test done to confirm the presence of pleural fluid. The lateral upright chest x-ray should be examined when a pleural effusion is suspected. In an upright x-ray, 75 mL of fluid blunts the posterior costophrenic angle. Blunting of the lateral costophrenic angle usually requires about 175 mL but may take as much as 500 mL. Larger pleural effusions opacify portions of the hemithorax and may cause mediastinal shift; effusions > 4 L may cause complete opacification of the hemithorax and mediastinal shift to the contralateral side.^{[citation needed]}

The presentation and natural history of asbestos-induced diffuse pleural thickening.
