The costodiaphragmatic recess, also called the costophrenic recess or phrenicocostal sinus, [1] is the posterolateral fringe of the pleural space, a potential space around the lung inside the pleural cavity.

2023年7月21日 · The costodiaphragmatic recesses (also called costophrenic angles) are the larger of the recesses located between the costal and diaphragmatic pleura of right and left pleural cavities. They occur at the costal reflection where the costal pleura becomes continuous with the diaphragmatic pleura.

Moreover, in ordinary inspiration the thin inferior margin of the lung does not extend as low as the line of the pleural reflection, with the result that the costal and diaphragmatic pleuræ are here in contact, the intervening narrow slit being termed the …

2023年7月24日 · The costomediastinal recess is located anteriorly where the costal and mediastinal pleura meet. The costodiaphragmatic recess is the most clinically important, as most fluid collections pool here. The pleural cavity always maintains a negative pressure.

2018年8月8日 · In the costodiaphragmatic recess, the costodiaphragmatic angle is disturbed creating widening of the angle whenever a small volume of fluid accumulates. In X-ray of chest, it appears as radiopaque darkness as a fluid line.

On a lateral view the costophrenic recesses are seen in the region of the anterior and posterior costophrenic angles formed by the chest wall and the dome of each hemidiaphragm. On a frontal chest X-ray the costophrenic angles should form acute angles which are sharp to a point.

2023年10月30日 · The costodiaphragmatic recess is situated between the diaphragmatic and costal pleura. The serous fluid continuously lubricates the pleural surface and makes it easy for them to slide over each other during lung inflation and deflation.

2018年8月8日 · The costodiaphragmatic recesses are the most dependent parts of the pleural cavities, for this reason the fluid of pleural effusion first accumulate at these sites. It’s found anteriorly between the costal and mediastinal pleurae …

2021年8月28日 · The costodiaphragmatic recesses are a clinically important space that provides a site for any fluid around the lungs to accumulate, including pleural effusions. They also provide a space for the lungs to expand into during forced inspiration.

2017年1月8日 · Costomediastinal recess: Is present anteriorly between the costal and mediatinal pleura. The left costomediastinal recess is larger due to the presence of cardiac notch along the anterior border of the left lung.
