title: Hereditary angioedema and pneumomediastinum.
abstract: Gastrointestinal and respiratory involvement is common in hereditary angioedema, laryngeal edema being the main cause of mortality in these patients. We report the case of an 18 year-old woman with a history of hereditary angioedema, who presented an episode of coughing and vomiting the night before, and who was diagnosed with pneumomediastinum as a complication of an episode of angioedema. We review the causes and pathogenesis of the mediastinic emphysema.
