Catamenial pneumothorax

Catamenial pneumothorax (CP) is the most common form of thoracic endometriosis syndrome, which also includes catamenial hemothorax, catamenial hemoptysis, catamenial hemopneumothorax and endometriosis lung nodules, as well as some exceptional presentations. Usually onset of lung collapse is less than 72 hours after menstruation. Most commonly occurs in women aged 30-40 years, but has been diagnosed in young girls as early as 10 years of age and post menopausal women (exclusively in women of menstrual age) most with a history of pelvic endometriosis. Diagnosis can be hinted by high recurrence rates of lung collapse in a woman of reproductive age with endometriosis. Moreover; CA-125 is elevated. Videoassisted thoracoscopy or medical thoracoscopy is used for confirmation. In our current work we will present all aspects of CP from diagnosis to treatment.
