What is the Costophrenic sinus?
The costodiaphragmatic recess, also called the costophrenic recess or phrenicocostal sinus, is the posterolateral fringe of the pleural space, a potential space around the lung inside the pleural cavity.
Where is the Hemidiaphragm located?
Each hemidiaphragm should appear as a smooth, domed contour. The right hemidiaphragm is usually a little higher than the left. The liver is located immediately inferior to the right hemidiaphragm. The stomach and spleen are located immediately inferior to the left hemidiaphragm.
What are the Costophrenic angles?
The costophrenic angles are formed by the points at which the chest wall and diaphragm meet. The costophrenic recesses contain the lower edges of the lungs which contact the diaphragm.
What does Costophrenic blunting mean?
pleural effusion
Blunting of the costophrenic angle (also known as blunting of the costophrenic sulcus) is a chest radiograph sign usually indicative of a small pleural effusion. It may be seen on either frontal or lateral erect projections.
What causes a Hemidiaphragm?
Injury to the phrenic nerve or hemidiaphragm is a direct cause of elevated hemidiaphragm. Indirect causes of elevated hemidiaphragm include a traumatic injury, neurologic disease, or cancerous processes within the thoracic and abdominal cavity.
What does elevated Hemidiaphragm mean?
Elevated hemidiaphragm: Elevation of half of the diaphragm, the muscle that separates the chest cavity from the abdomen and that serves as the main muscle of respiration. The elevation of a hemidiaphragm is a significant sign of a problem.
What does blunting of the right and left Costophrenic angles mean?
Why is the right hemidiaphragm higher than the left?
However, they received little attention from the medical community. Over the past three decades, the classic teaching has been that the diaphragm is elevated in the right side because the liver is in the right side.

What does Costophrenic mean in medical terms?
Medical Definition of costophrenic : of or relating to the ribs and the diaphragm.
What does blunting of costophrenic angle mean?
Blunting of a costophrenic angle is the classic sign for pleural effusion. It is important to note that minor blunting may be caused by scarring or chronic atelectasis. Effusions first become apparent on lateral upright radiographs with blunting of the posterior costophrenic angle.
