A case of catamenial pneumothorax with diaphragmatic fenestrations.

BACKGROUND

Considerable controversy exists with regards to the physiopathogenesis of catamenial pneumothorax. The rarity of catamenial pneumothorax makes understanding of its pathophysiology and verification of etiological mechanisms difficult.

OBJECTIVE

To contribute evidence to the knowledge base on the pathogenesis of catamenial pneumothorax.

CASE REPORT

We describe a case of catamenial pneumothorax with images that substantiate the pore hypothesis as a cause of recurrence of air in the pleural cavity in this patient.

CONCLUSION

Our case report contributes evidence that transperitoneal migration of endometrial implants may occur through diaphragmatic fenestrations. Surgical options may be more viable to prevent recurrent pneumothoraces in such patients.
