Sharp costophrenic angles bilaterally refer to the angles formed between the diaphragm and the ribs in the thoracic cavity. On a chest X-ray, sharp bilateral costophrenic angles indicate a normal finding. Conversely, blunting of the costophrenic angle suggests underlying pathology—such as pleural effusion, adhesions, pulmonary infection, or other thoracic tissue abnormalities. In such cases, patients should seek medical evaluation at a hospital and undergo appropriate diagnostic tests under physician guidance to determine the underlying cause and receive targeted treatment.
