Anteromedial pneumothorax in a neonate: 'the diagnostic dilemma' and the importance of clinical signs.

A premature neonate born at 32 weeks of gestation was admitted to the neonatal unit with respiratory distress syndrome. The infant received late rescue surfactant therapy with continued mechanical ventilation in view of continuous positive airway pressure (CPAP) failure. Owing to worsening distress and an air leak, he was switched over to high-frequency oscillatory ventilation. The air leak required drainage for possible pneumopericardium. This was initially attempted ineffectually with echo-assisted pericardial drainage, and later successfully with the use of chest tubes for anteromedial pneumothorax. 2014 BMJ Publishing Group Ltd.
