In affected people the bronchioles may become damaged and inflamed leading to extensive scarring that blocks the airways.
Bronchiolitis obliterans is an inflammatory condition that affects the lungs tiniest airways the bronchioles. Popcorn lung is a serious and irreversible condition in which the tiny air sacs in the lungs become scarred and constricted which results in no air movement or O2 - CO2 exchange in the lungs.

Andor fatigue and wheezing in the absence of a cold or asthma. Bronchiolitis obliterans is an irreversible and chronic condition with available treatments that can slow progression and reduce the severity of your symptoms. Bronchiolitis Obliterans Syndrome BOS BOS is a clinicopathologic common syndrome of progressive and irreversible airway obstruction with a declining DL co that occurs as a late complication in graft function with an incidence of almost 50 by the fifth year after transplantation Figure 78-21.
Thus the bronchiolitis obliterans became known as popcorn lung. Viral outbreaks occur every winter and affect children under the age of 1 year old. C hronic rejection of the lung allograft is defined as a fibrosing process affecting the lung which primarily affects the conducting airways and the pulmonary vasculature.
Bronchiolitis obliterans BO is a disease of small airways that results in progressive dyspnea and airflow limitation. Bronchiolitis obliterans is also known as obliterative bronchiolitis or constrictive bronchiolitis.

The signs and symptoms of BOOP vary but often include shortness of breath a dry cough and fever.
Several weeks following cessation of irradiation the patient developed hypoxemia and reticulonodular densities within the radiation port. Bronchiolitis obliterans organizing pneumonia BOOP is a lung disease that causes inflammation in the small air tubes bronchioles and air sacs alveoli.
