Definition / general
  • Portion of bronchial tree with normal branching pattern, but without any demonstrable connection to the central bronchial tree
  • Congenital abnormality due to focal interruption of lobar, segmental or subsegmental bronchus with associated peripheral mucus impaction (bronchocele, mucocele) and hyperinflation of obstructed lung segment; most commonly affects apicoposterior segmental bronchus of left upper lobe, then segmental bronchi of right upper, middle and lower lobes
  • Cause unknown, but appears to occur before birth
  • Lobar bronchial atresia can mimic mainstem bronchial atresia on mid trimester ultrasound (Ultrasound Obstet Gynecol 2011;37:110)
