Which are the symptoms of Catamenial Pneumothorax?

Catamenial pneumothorax is a rare condition characterized by the recurrent collapse of the lung (pneumothorax) occurring in temporal association with the menstrual cycle, typically within 72 hours of the onset of menses. The primary symptoms include sudden, sharp chest pain and shortness of breath that coincide with menstruation, often resulting from thoracic endometriosis.

What are the primary symptoms of Catamenial Pneumothorax?

The hallmark of Catamenial Pneumothorax is the predictable timing of symptoms. Most patients experience a sudden onset of pleuritic chest pain—described as a sharp, stabbing sensation—often localized to the right side of the chest. This is frequently accompanied by dyspnea (difficulty breathing) and a dry, non-productive cough. Because Catamenial Pneumothorax is intrinsically linked to ectopic endometrial tissue within the thoracic cavity, symptoms typically emerge during the first few days of the menstrual period.

How do symptoms manifest and progress?

While some individuals experience mild, self-limiting air leaks, others face severe, life-threatening respiratory distress. Early warning signs for those diagnosed with Catamenial Pneumothorax include:

• Recurrent chest pain that consistently aligns with the menstrual cycle.


• Shoulder tip pain, which can indicate diaphragmatic irritation.


• Increased shortness of breath during physical exertion during menses.


• Hemoptysis (coughing up blood), though this is less common.

Which symptoms most impact daily life?

The chronic, cyclical nature of Catamenial Pneumothorax can significantly impact quality of life. The psychological burden of anticipating a potential lung collapse every month often leads to anxiety and social withdrawal. Furthermore, the physical pain and the necessity for repeated emergency interventions can disrupt work, education, and personal relationships for the 21 members currently tracking this condition on DiseaseMaps.org.

When should you seek emergency care?

Any patient with a history of Catamenial Pneumothorax must seek immediate emergency medical attention if they experience:

• Sudden, severe chest pain that does not subside.


• Rapid, shallow breathing or an inability to catch one's breath.


• Cyanosis (bluish tint to lips or fingernails).


• Dizziness, confusion, or a rapid heart rate.

Next steps

• Consult a thoracic surgeon or a gynecologist specializing in endometriosis to discuss hormonal suppressive therapies.


• Maintain a detailed symptom diary to track the timing of chest pain relative to your menstrual cycle.


• Connect with the Catamenial Pneumothorax community at DiseaseMaps.org to share experiences and coping strategies.


• Seek urgent imaging (chest X-ray or CT scan) at the first sign of recurrence during menses.
