We read with interest the paper by Leonidas et al entitled, "Persistent Localized Pulmonary Interstitial Emphysema and Lymphangiectasia: A Causal Relationship?" (Pediatrics 64: 165, 1979) We have reported1 our experience with five neonates in whom clinical, roentgenographic, and morphologic findings were nearly identical with those demonstrated by Leonidas et al. However, with respect to their hypothesis that intralymphatic air dissection is responsible for the apparent pulmonary lymphangiectasia and persistent pulmonary overinflation, we wish to point out that the authors have failed to establish one crucial point.
