title: [Spontaneous multiloculated pneumomediastinum in a newborn: case report].
abstract: Spontaneous pneumomediastinum in a term baby without assisted ventilation or known underlying pulmonary disease is uncommon. The authors present a case report of a term baby delivered by caesarean that developed mild respiratory distress after birth. The pulmonary X -ray on day 2 showed an abnormal gas lucency adjacent to the left cardiac border elevating thymic border indicative of pneumomediastinum. Our case demonstrates two unique features of neonatal pneumomediastinum - the presence of multiple internal septae and its tendency to loculate locally. The authors present this case for its rarity and the specific imagiological aspects.
