<unk>  is a medical emergency because it comes with severe pain and decreased lung function. A chest tube should be inserted after clinical assessment. This releases the air and menstrual blood, and the lung can re-expand.
Surgery, hormonal treatments and combined approaches have all been proposed, with variable results in terms of short and long term outcome. Surgical removal of the endometrial tissue should be endeavoured during menstruation for optimal visualization of the cyst. Pleurodesis may also be helpful. Menstruation and accompanying lung collapse can be suppressed with hormone therapy, like with Lupron Depot, danazol or extended cycle combined oral contraceptive pills.
