Abstract

Many countries have introduced newborn screening for cystic fibrosis to facilitate diagnosis prior to the development of lung disease. Although most infants with cystic fibrosis are asymptomatic from a respiratory point of view at diagnosis, structural lung disease has been detected by computed tomography. We present a case of an asymptomatic infant with cystic fibrosis diagnosed following newborn screening who had endobronchial infection with Pseudomonas aeruginosa and radiological evidence of bronchiectasis at 3 months of age.
