Computed tomography of diffuse interstitial lung disease in children

Unlike diseases of the airways, interstitial lung diseases in childhood are exceedingly rare and are usually associated with significant morbidity and mortality. Interstitial lung disease in the paediatric age group is a particular diagnostic challenge because the clinical presentation and radiographic features are so non-specific. High resolution computed tomography (HRCT) has proved its worth in adults with interstitial lung disease and has a role, albeit more limited, in the non-invasive evaluation of paediatric interstitial lung disease.
