Q; What is Catamenial pneumothorax?

A; Catamenial pneumothorax is a rare condition characterized by a pneumothorax coinciding with the onset of menses. It is almost always right-sided, and generally occurs in women in their thirties and forties.


Exact etiology is unknown but endometriosis is suspected with possible diaphragmatic fenestrations. Damage to endometriosis with air passes into the pleural space through these holes. It may accompany with hemothorax if blood from endometriosis enters pleural cavity.


Acute treatment is drainage of pneumo (air), Chest tube, Pleurodesis in recurrent cases and surgical closure of diaphragmatic fenestrations if required.
Referral should be made to Gyn. service for hormonal and related management of endometriosis.
