The paper reports a case of left-sided catamenial pneumothorax in a 33-year-old woman with a history of pelvic endometriosis, occurring at the end of a course of low-dose contraceptive pills. Chest CT identified a left upper lobe bulla, and the patient underwent partial lung resection; immunohistochemistry confirmed endometrial stromal tissue in the visceral pleura, with no observed diaphragm abnormalities, supporting this pleural lesion as the cause. The main limitation is that the report represents a single case and cannot establish broader prevalence or mechanisms beyond this patient. This paper is centrally about endometriosis — specifically thoracic (visceral pleural) endometriosis causing left-sided catamenial pneumothorax.

Abstract

Catamenial pneumothorax (CP) is generally caused by intraperitoneal air leaking from the uterus into the thoracic cavity via a defect in the endometrial tissue of the diaphragm and is usually detected in the right thorax. We report a case of left-sided CP caused by endometriosis in the visceral pleura and with no abnormal findings in the diaphragm. A 33-year-old female patient presented at the end of a course of low-dose contraceptive pills for pelvic endometriosis, with spontaneous pneumothorax in the left chest. Chest CT revealed a bulla in the left upper lung lobe. The patient underwent partial resection of the lung. Immunohistochemistry confirmed the presence of endometrial stromal tissue in the visceral pleura and confirmed this as the cause of pneumothorax since there were no observable abnormalities in the diaphragm. This case suggests that immunohistochemical examination of patients with spontaneous pneumothorax can detect alternative endometrial lesions.
