[Traumatic pulmonary pseudocysts].

Abstract

Two cases of traumatic pulmonary pseudocysts in young patients are presented. Blunt chest injuries resulting from traffic accidents were the causes in both cases. Air cavities were seen on chest films 12 hours and one hour, respectively, after trauma. In both cases, self-limited hemoptysis preceded the appearance of an air-fluid level on X-rays. The diagnoses of pulmonary pseudocyst were made after excluding other possible cause and the outcomes were satisfactory after treatment of symptoms and associated lesions.
