Propranolol for the Treatment of Lymphatic Malformations in a Neonate - A Case Report and Review of Literature.

Lymphatic malformations in neonates often manifest as a chylothorax, and although rare, morbidity and mortality can be significant. First-line treatment with medium-chain triglyceride-enriched formulas, or enteric rest with total parenteral nutrition, are not always successful. We describe the case of a premature neonate with trisomy 21 who presented with bilateral pleural effusions and a pericardial effusion that worsened with the initiation of enteral nutrition.
