[Pulmonary pseudocysts. A rare entity after thoracic injury].

Post-traumatic pulmonary pseudocyst is a rare manifestation of blunt thoracic injury. Young adults and adolescents are predominantly affected. Here we report the successful outcome of post-traumatic pseudocysts secondary to severe lung contusion with severe intrathoracic haemorrhage in both lower lobes and the upper right lobe by aggressive coagulation management, kinetic therapy/postural drainage and control of secondary infection.
