Der katameniale Pneumothorax – ein Chamäleon in Klinik und Pathogenese
Catamenial pneumothorax, a rare condition, is characterized by recurrent, menstruation-dependent pneumothorax associated with endometriosis of the pleura, lungs, or diaphragm.

The paper describes a rare syndrome, catamenial pneumothorax, and reports two clinical case presentations of women treated over the prior two years whose pneumothoraces recurred in relation to menstruation. The authors document differing symptom patterns and, after thoracic surgery, different pathological distributions of endometriosis—one case showing lesions limited to the diaphragm and the other confined to the parietal and visceral pleura—suggesting different pathogenetic mechanisms for air entry sites. Both patients underwent lung apical resection and pleural procedures, followed by hormonal treatment after diagnosis confirmation, and no recurrences were reported during follow-up. The paper specifically frames the need to consider catamenial pneumothorax even when endometriosis is not known, while the main limitation is that conclusions are based on only two cases. This paper is centrally about endometriosis — it focuses on catamenial pneumothorax caused by pleural and/or diaphragmatic endometriosis.
