Fig. 3. 2-year-old boy with biopsy-proven desquamative interstitial
pneumonitis and Gaucher's disease. Thin-section CT scan shows widespread
ground-glass opacification and denser parenchymal opacification in dependent
lung.

Fig. 4. 13-year-old girl with biopsy-proven lymphocytic interstitial
pneumonia. Patient was immunocompromised because of postviral neutropenia.

Fig. 5. 8-year-old boy with biopsy-proven pulmonary lymphangiomatosis.
Thin-section CT scan shows bilateral pleural effusions, thickened interlobular
septa, and thickened bronchovascular bundles. Features are also seen in
congenital lymphangiectasia, and this patient was confidently diagnosed by
both observers as having latter condition.
