| Enlarged and edematous lungs, consolidation, hemorrhage, bronchopneumonia, and acute bronchiolitis were also noted. |
| When constrictive bronchiolitis occurs with no identifiable cause, it is referred to as cryptogenic constrictive bronchiolitis. |
| Vascular invasion, mitosis, and cell pleomorphism are not observed in cases of bronchiolitis obliterans organizing pneumonia. |
| Not to be confused with bronchitis, bronchiolitis is an inflammation of the bronchioles, the smallest branches of the bronchial tree. |
| Symptoms of bronchiolitis include rapid breathing, a cough, wheezing, and fever. |
| In children, fever associated with dyspnea usually implies an infectious cause, such as pneumonia, croup, or bronchiolitis. |
