Catamenial pneumothorax, often linked to endometriosis, may stem from diaphragmatic defects. Surgical repair of these defects offers a promising treatment for recurrent cases.

Area of Science:

  • Pulmonology
  • Thoracic Surgery
  • Gynecology

Background:

  • Catamenial pneumothorax (CP) is spontaneous pneumothorax linked to menstruation, often considered a manifestation of thoracic endometriosis.
  • The exact etiology of CP remains unclear, as endometriosis does not fully explain all recurrent, cyclical episodes.
  • This condition necessitates further investigation into underlying causes beyond endometriosis.

Observation:

  • A 37-year-old woman experienced recurrent right-sided pneumothorax and chest pain associated with her menstrual cycles.
  • Previous treatments, including surgical pleurodesis and hormonal therapy, were ineffective.
  • Surgical re-exploration revealed multiple diaphragmatic fenestrations.

Findings:

  • Surgical closure of diaphragmatic fenestrations resulted in the resolution of pneumothorax symptoms.

  • The patient remained asymptomatic six months post-surgery without recurrence.
  • This case highlights diaphragmatic defects as a potential primary cause of CP.

    • Implications:

    • Diaphragmatic defects may be a more common underlying pathology in catamenial pneumothorax than previously recognized.
    • Surgical inspection and repair of diaphragmatic fenestrations should be considered for patients with refractory CP.
    • This approach may offer a definitive treatment option for recurrent catamenial pneumothorax.
