The article discusses a case of a 72-year-old man who was presented with chronic obstructive pulmonary disease (COPD). It says that the patient experiences retraction of the lower rib cage margin and the chest radiograph presented distention of the lungs associated with the flattening of the diaphragm. It also mentions that expiratory flow limitation results to incomplete gas trapping and emptying of the lungs that induces pulmonary hyperinflation which is the cause of diaphragm flattening.
