A new case report describes a rare problem called catamenial pneumothorax. This means a lung collapses around the time of a woman's period. It happens again and again, often just before or during monthly bleeding. The report shares two cases and reviews other published cases.
Catamenial pneumothorax is part of a larger condition called thoracic endometriosis syndrome. Tissue like the lining of the womb grows outside the womb, sometimes in the chest. When hormones change during the menstrual cycle, this tissue can cause a lung to collapse. The result is sudden chest pain and trouble breathing.
Because the symptoms follow a monthly pattern, doctors may not connect them to periods. Many women are treated for a single collapsed lung without asking about their cycle. This can lead to repeated episodes and delays in care. The report calls for more awareness so that women get the right diagnosis sooner.
The study is only a case report with a literature review, not a large trial. It cannot prove cause and effect. Still, it highlights a real problem that is often overlooked. Women who have repeated lung collapses should tell their doctor if the episodes happen around their period. That simple detail can make a big difference in getting proper care.
Common questions
What is catamenial pneumothorax?
Catamenial pneumothorax is a type of collapsed lung that happens in women of reproductive age during the perimenstrual period. According to this case report, it is characterized by spontaneous and recurrent pneumothorax. It is part of thoracic endometriosis syndrome. The report aims to raise awareness so it is not missed or misdiagnosed.
Who does this affect?
This case report describes the condition in women of reproductive age. The report included two cases. Because the sample size is very small, it is not known how common this is or whether it affects all women equally. If you have concerns, talk with your doctor.
Is this a proven cause?
No. This is a case report with a literature review, not a clinical trial. It describes an association between recurrent pneumothorax and menstruation in two women. It cannot prove that menstruation causes the collapsed lung. More research is needed to understand the link.
What are the limitations of this report?
The main limitation is the very small sample size of two cases. No treatments, outcomes, follow-up, or safety information were reported. As a case report and literature review, it cannot show cause and effect or how often this happens. The findings should be considered early and descriptive.
