Abstract
A fourteen-month-old male with a bronchial foreign body, a peanut, complicated with pneumomediastinum and cervical subcutaneous emphysema was reported. The pneumomediastinun and subcutaneous emphysema was revealed by chest X-ray examination. MRI was found useful for visualizing the trapped foreign body as well as for the diagnosis of the complications. After removal of the foreign body using ventilation bronchoscopy, the pneumomediastinum and subcutaneous emphysema disappeared spontaneously within five days.
