Trauma: an unusual aetiology of pulmonary pseudocyst.

Traumatic pulmonary pseudocyst due to blunt chest trauma is rare. It is a clinical entity that manifests itself with minor clinical and major radiological signs. We report a case of a 16-year-old girl, who during an attack by a violent cow sustained a chest impact that resulted in a traumatic pulmonary pseudocyst, confirmed with a computed tomographic (CT) scan of the chest. The patient recovered with conservative management.
