Congenital pulmonary lymphangiectasis mimicking congenital pulmonary interstitial emphysema in a patient with congenital diaphragmatic hernia

Congenital pulmonary lymphangiectasis is a rare abnormality of the lung characterized by dilated pulmonary lymphatic vessels. The diagnosis of congenital pulmonary lymphangiectasis is challenging due to its unspecific presentation, as well as possible radiological imitation of interstitial emphysema. We present a patient where diagnosis was hampered by the extremely rare combination of pulmonary lymphangiectasis and congenital diaphragmatic hernia.
