Abstract
During the acquisition of a series of 92 children with interstitial lung disease (ILD) over a 14 year period, a significant minority (8/92 or 9%) were initially diagnosed as having ILD, but were subsequently found to have a variety of arterial, venous, and/or capillary disorders that explained their initial pulmonary findings. This subgroup of patients has had a very high morbidity and mortality, with only three of eight patients currently surviving. The presentation, evaluation, and natural history of these eight children were reviewed. We developed a strategy of cardiac and pulmonary evaluation for children presenting with clinical and radiographic features of ILD that helped us to identify rapidly those with pulmonary vascular disorders.
