Traumatic pulmonary pseudocysts (TPP) are a rare complication of chest trauma, with most cases occurring before the age of 30, due to the greater elasticity of the chest wall. They can be identified on a chest radiography, but computed tomography (CT) is more sensitive in early detection and differential diagnosis. We present the case of a 14-year-old adolescent who was admitted for chest trauma after being run over by a car. Identification of cystic lesions in the chest CT prompted an investigation of possible infectious and thromboembolic aetiology, which was negative. The diagnosis of TPP was established, with complete resolution of the lesions after three months. Although it is a rare entity, TPP should be considered in cases of chest trauma in order to avoid unnecessary diagnostic and therapeutic procedures. In the absence of complications, treatment is conservative and the prognosis is good.
