A Case of Cystic Pneumomediastinum with Thymic Hyperplasia in a Newborn / 소아알레르기및호흡기학회지

ABSTRACT

Spontaneous pneumomediastinum in a term newborn without mechanical ventilation or underlying lung disease is rare. We present a case of a newborn baby who developed respiratory distress after birth and cystic pneumomediastinum which improved spontaneously with thymic hyperplasia as demonstrated on chest radiography, CT and MRI. The combination of cystic pneumomediastinum and thymic hyperplasia in a newborn has not been reported, thus far.
