[Congenital diaphragmatic hernia with symptoms in adulthood]

A left-sided diaphragmatic defect in the centrum tendineum of a 27-year-old female patient, who complained about dyspnea and hemoptysis, will be reported concerning symptoms, diagnostic procedure and operative therapy. This presumably congenital diaphragmatic defect caused an organ prolapse into the pleural cavity probably enhanced by an increased intraabdominal pressure during pregnancy and delivery. The defect was primarily closed after laparotomy. No plastic surgical reconstruction with autologous or homologous materials was necessary.
