title: Aberrant positioning of mediastinal mass in air space disease.
abstract: A seven-year-old black male child presented to the District of Columbia General Hospital children's emergency room with a one-day history of wheezing. A chest x-ray was obtained prior to admission to rule out foreign body or air space disease. The radiological evaluation was consistent with the clinical diagnosis of asthma.
