Resumo

O pneumomediastino espontâneo num recém-nascido (RN) de termo não submetido a ventilação mecânica ou sem patologia pulmonar subjacente é uma entidade rara. A existência de septos internos e a tendência à loculação são particularidades do pneumomediastino neonatal. Os autores apresentam o caso clínico de um recém-nascido de termo, fruto de uma gravidez vigiada, com ecografias fetais normais, nascido de cesariana, sem necessidade de reanimação, que iniciou gemido e sinais de dificuldade respiratória às 2 horas de vida. A radiografia do tórax efectuada em D2 mostrou imagem de hipertransparência adjacente ao bordo cardíaco esquerdo e retroesternal e hipotransparência do lobo superior esquerdo. A tomografia axial computorizada torácica, realizada em D5, evidenciou pneumomediastino multiloculado com múltiplos septos internos.

Os autores apresentam este caso pela sua raridade e aspectos imagiológicos específicos

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.
