title: Catamenial pneumomediastinum.
abstract: A patient with known pelvic endometriosis suffered from recurrent episodes of retrosternal pain in the chest at the time of menstruation. Evaluation during an episode revealed subcutaneous emphysema of the neck and a pneumomediastinum without pneumothorax. This is the first report in the English literature of pneumomediastinum due to endometriosis which was probably recurrent.
