title: Pneumoperitoneum associated with catamenial pneumothorax in women with thoracic endometriosis.
abstract: OBJECTIVE
  To elucidate the pathophysiology of catamenial pneumothorax (CP) due to thoracic endometriosis and support the theory of the transdiaphragmatic passage of air from the genital tract through diaphragmatic perforations caused by endometrial implants.
  
  
  METHODS
  Three case reports.
  
  
  METHODS
  Academic hospital.
  
  
  METHODS
  Three women with pneumoperitoneum concomitant to CP.
  
  
  METHODS
  Thoracic/abdominal computed tomography scans and chest x-rays.
  
  
  METHODS
  Presence of pneumoperitoneum coexisting with CP.
  
  
  RESULTS
  The observation of pneumoperitoneum associated with CP supports the theory of the transdiaphragmatic passage of air, which implies the occurrence of a pneumoperitoneum as an intermediate step.
  
  
  CONCLUSIONS
  Our three cases strongly support the theory of the transdiaphragmatic passage of air in the pathogenesis of CP.
