Catamenial pneumothorax is a rare form of recurrent lung collapse associated with the menstrual cycle, most commonly caused by thoracic endometriosis. It is primarily referred to by this specific clinical name, though it is frequently categorized under the broader umbrella of Thoracic Endometriosis Syndrome (TES). What are the common synonyms for Catamenial Pneumothorax? While Catamenial pneumothorax is the standard medical term used in current clinical literature, you may encounter several synonyms depending on the historical context or the specific pathophysiology being described.

Catamenial pneumothorax is a rare form of recurrent lung collapse associated with the menstrual cycle, most commonly caused by thoracic endometriosis. It is primarily referred to by this specific clinical name, though it is frequently categorized under the broader umbrella of Thoracic Endometriosis Syndrome (TES).
What are the common synonyms for Catamenial Pneumothorax?
While Catamenial pneumothorax is the standard medical term used in current clinical literature, you may encounter several synonyms depending on the historical context or the specific pathophysiology being described. These include:
- Thoracic endometriosis-related pneumothorax
- Menstrual pneumothorax
- Cyclical pneumothorax
- Catamenial spontaneous pneumothorax
These terms are often used interchangeably, although "catamenial" specifically denotes a condition that occurs in relation to the menses (menstruation).
Why does Catamenial Pneumothorax have multiple names?
The nomenclature for Catamenial pneumothorax reflects the evolution of our understanding of the disease. Historically, clinicians identified the temporal link between menstruation and lung collapse, leading to the descriptive term "catamenial." As medical research advanced, it was discovered that most cases of Catamenial pneumothorax are actually manifestations of thoracic endometriosis. Consequently, some specialists prefer the term "Thoracic Endometriosis Syndrome" (TES) to encompass the full spectrum of the disease, which can include hemothorax (blood in the lung cavity) and lung nodules, in addition to pneumothorax.
How is this condition classified in medical systems?
In major international classification systems, Catamenial pneumothorax is generally categorized under the secondary spontaneous pneumothorax codes or specific endometriosis-related codes. Because it is a rare presentation of a gynecological condition occurring in the thoracic cavity, it does not always have a unique, standalone ICD-10 code, leading to its classification under:
- ICD-10 N80.6: Endometriosis of the pleura.
- ICD-10 J93.1: Spontaneous pneumothorax.
- Orphanet: Often listed under the umbrella of thoracic endometriosis (ORPHA: 479965).
Currently, Catamenial pneumothorax remains the most widely recognized term by pulmonologists and thoracic surgeons worldwide.
