"Most cases present with respiratory distress within the first six months of life - about 30% at birth and 50% within 1 month 5. Respiratory distress may be accompanied by wheezing and can develop rapidly or slowly; some cases may be unsuspected for years, depending on the size of the abnormal lobe."
"Histology may show enlarged distal airways and airspaces together or normal conducting airways with dilated and abnormally numerous alveoli. Sometimes the bronchial cartilage is abnormal or there are abnormal mucosal folds or granulation tissue which might cause obstruction. There is no emphysema."
