Hello, I went through your query, Restrictive lung diseases are characterized by reduced lung volume, either because of an alteration in lung parenchyme or extra parenchymal that is because of a disease of the pleura, chest wall, or neuromuscular apparatus. Your reports shows extra parenchymal(lung tissue is normal) . Please talk to your doctors for finding further cause.
