Abstract Congenital chylothorax should be considered in neonates with symptoms and imaging consistent with pleural effusion, but analysis of the pleural effusion is necessary to confirm chylothorax. Lymphangiogram can identify a leak or highlight a structural lymphatic anomaly and is useful in guiding therapy. However, this case adds to the recent evidence in the literature that lymphangiography alone can resolve a lymphatic leak. Further research should be done on the efficacy of therapeutic lymphangiography to further elucidate its role in congenital chylothorax management.
