Traumatic pulmonary pseuodocysts: two case reports.

Traumatic pulmonary pseudocyst (TPP) is a rare complication, sometimes encountered after blunt thoracic trauma and even more rarely following penetrating injuries. It is more common among pediatric and young adult patients. Although TPP is usually benign in nature, complications associated with hemoptysis and secondary infection may develop. The treatment is conservative. In this report, we present two rare cases of TPP occuring after a high-speed accident and a stab wound injury, where conservative treatment provided good outcomes.
