This case report presents evidence of diaphragmatic fenestrations contributing to transperitoneal migration of endometrial implants, potentially causing recurrent catamenial pneumothorax.

Abstract

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.
