Summary Summary

Catamenial pneumothorax is an extremely rare condition that affects women. Pneumothorax is the medical term for a collapsed lung, a condition in which air or gas is trapped in the space surrounding the lungs causing the lungs to collapse. Women with catamenial pneumothorax have recurrent episodes of pneumothorax that occur within 72 hours before or after the start of menstruation. The exact cause of catamenial pneumothorax is unknown and several theories have been proposed. Many cases are associated with the abnormal development of endometrial tissue outside of the uterus (endometriosis). Some believe that catamenial pneumothorax is the most common form of thoracic endometriosis (a condition in which the endometrial tissue grows in or around the lungs). A diagnosis of catamenial pneumothorax is usually suspected when a woman of reproductive age and with endometriosis has episodes of pneumothorax. Treatment is with hormones and surgery.^[1]^[2]^[3]

Symptoms Symptoms

In the vast majority (87.5%-100%) of catamenial pneumothorax the right side is involved, but there are cases in which both sides or only the left side is involved. Catamential pneumothorax is associated with thoracic and pelvic endometriosis in many cases.

The typical clinical manifestation of the condition involves spontaneous pneumothorax before or during periods (menses), usually presented with:^[1]^[2]^[4]

• Pain
• Dyspnea
• Cough
• Shoulder pain
• Pain in the chest

In cases with endometriosis it may present as:^[1]^[2]^[4]

• Pelvic endometriosis - Generally, the symptoms include pain during periods and during sex and infertility.
• Thoracic endometriosis - Catamenial pneumothorax is the most common symptom of thoracic endometriosis syndrome (72-73% of the cases). Other symptoms of thoracic endometriosis syndrome include blood collecting in the space between the chest wall and the lung (catamenial hemothorax), coughing up blood (catamenial hemoptysis), air and blood in the chest space (catamenial hemopneumothorax) and endometriosis lung nodules.

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.

Cause Cause

The exact cause is not known. However, spontaneous collapse of the lung (pneumothorax) occurs in 72% to 73% of cases of thoracic endometriosis. Thoracic endometriosis is a condition in which endometrial tissue is present in the chest (thoracic) cavity. It is more often seen in women who are about 34 years old. Thoracic endometriosis can be found in most cases of catamenial pneumothorax.^[1]

Pneumothorax associated with endometriosis may also occur without being related with menstruation (non-catamenial pneumothorax) even in cases with no symptoms or without diagnosis of pelvic endometriosis.^[1]

Diagnosis Diagnosis

The diagnosis should be suspected in women of reproductive age who have several episodes of spontaneous lung collapse (pneumothoraces) and have endometriosis. Medical thoracoscopy or video-assisted thoracoscopy may confirm the diagnosis.^[1]

Treatment Treatment

Treatment of choice is with surgery, with video-assisted thoracoscopic surgery (VATS). Conventional thoracotomy may be occasionally necessary, particularly in repeat operations. It is very important to examine the large, thin tissue lining around the outside of the lungs and the inside of the chest cavity (pleura).^[1]

Hormonal treatment with surgery prevents the repeat of catamenial and/or endometriosis-related pneumothorax. Gonadotrophin-releasing hormone (GnRH) for 6 to 12 months after the surgery is also often recommended.^[1]
