Catamenial pneumothorax is a rare primary spontaneous pneumothorax associated with the menstrual phase and is the most common manifestation of thoracic endometriosis syndrome. We report a case of a 32‐year‐old woman with a history of endometriosis who presented to the emergency ward with a chief complaint of dyspnea and right‐sided chest pain, and a chest X‐ray showed a right pneumothorax. Initial management was by placing a chest tube to expand the right lung. The patient underwent a video‐assisted thoracoscopy and talc pleurodesis, during which we found multiple perforations in the tendinous part of the diaphragm. A partial resection of the tendinous part of the diaphragm was done. Our review indicated that primary spontaneous pneumothorax in women should be suspected as catamenial pneumothorax due to thoracic endometriosis. The gold standard procedure for diagnosis and treatment is surgery. Hormonal therapy is an effective choice to prevent and reduce post‐operative recurrence.
