Cryptogenic organizing pneumonia (COP) is a form of idiopathic interstitial pneumonia characterized by lung inflammation and scarring that obstructs the small airways and air sacs of the lungs (alveoli). Signs and symptoms may include flu-like symptoms such as cough, fever, malaise, fatigue and weight loss. COP often affects adults in midlife (40 to 60 years of age). The exact underlying cause of the condition is unknown (idiopathic). Treatment varies based on the severity of the condition but generally includes glucocorticoids.
