A heterogeneous group of 11 children with atelectasis persisting longer than one month were investigated for the causes using chest computed tomography and fiberoptic bronchoscope. Four young infants had right upper lobe (RUL) posterior segmental atelectasis simulating RUL lobar collapse in plain chest films; all had only two visible segmental bronchi by bronchoscopic examination. Intraluminal obstruction in the central airway was not a common cause of pediatric chronic atelectasis in this small series of patients. Only one obstructive atelectasis caused by dilated pulmonary arteries was detected in this study. Two patients with pre-existing neuromuscular diseases showed multiple atelectasis. The atelectatic lobes do not spontaneously re-inflate following flexible bronchoscopy. Investigations involving a larger number of cases are needed to substantiate the etiologies and to guide specific therapy for those children with chronic atelectasis.
