Pneumoscrotum after blunt chest trauma.

Pneumoscrotum, the accumulation of air inside the scrotum, is a rare complication associated with blunt chest trauma. We report a case of severe subcutaneous emphysema, pneumothorax, pneumomediastinum, pneumopericardium, and pneumoscrotum after blunt chest trauma in a 44-year-old man. He presented with progressive swelling of the neck that descended to the chest, abdomen, both legs, and scrotum. Radiography and computed tomography of the chest and abdomen confirmed the diagnosis of a tracheal injury complicated by severe subcutaneous emphysema, pneumothorax, pneumomediastinum, pneumopericardium, and pneumoscrotum. Primary repair of the tracheal injury was performed, and he was weaned successfully from the ventilator by day 5. He was discharged on day 7.
