Posttraumatic Pulmonary Pseudocyst: A Rare Complication of Blunt Chest Trauma

Abstract

Posttraumatic pulmonary pseudocyst is a rare cavitary lesion lacking an epithelial lining, which develops within the pulmonary parenchyma after blunt chest trauma. Such pseudocysts develop most commonly in children and young adults. The clinical course is usually benign with spontaneous resolution of the radiologic manifestations within 2 to 4 months after trauma. A young male injured in a motor vehicle accident, sustaining a posttraumatic pulmonary pseudocyst, is presented here. © Georg Thieme Verlag KG.
