Chest non-penetrating trauma often caused by pulmonary contusion and pulmonary hemorrhage, but rare cavitary lesions or pseudocysts, the authors reported in 2 cases. Example 1, female, 21 years old. Due to a car accident caused by multiple fractures and pulmonary contusion. On admission, the chest radiograph was normal. A few days later, the edge of the lower lobe of the right lung appeared fuzzy high-density edge. After 6 days, it showed a thin, hollow cavity with a clear boundary of 6 cm × 8 cm and contained gas. CT showed a large thin-wall cystic lesions, CT value of 90 ~ 100HU, 6 weeks after the lesion was significantly reduced (2cm × 3cm). Example 2, female, 28 years old. Due to accident caused by multiple fractures, retroperitoneal hemorrhage, lung, heart, kidney contusion, liver and spleen rupture. Chest radiograph
