title: Two cases of pulmonary tuberculosis presenting with unilateral pulmonary hyperinflation in infancy.
abstract: Two infants with recurrent obstructive symptoms attracted attention because of massive radiologically detected unilateral pulmonary hyperinflation. Further diagnostic procedures including bronchoscopy, revealed a pulmonary tuberculosis with lymph nodes encroaching on the bronchi. Steady improvement of clinical symptoms and hyperinflation was noted under combined antituberculotic therapy including systemic steroids.
  
  
  CONCLUSIONS
  Our two cases demonstrate that the differential diagnosis of unilateral pulmonary hyperinflation and wheezing in infancy should consider valvular stenosis by encroaching lymph node due to pulmonary tuberculosis.
