Abstract

Catamenial pneumothorax (CP) is an uncommon condition, usually associated with thoracic endometriosis syndrome (TES). TES is characterized by the presence of endometriotic lesions in pleura and lung parenchyma and presents with various clinical signs and symptoms, including catamenial pneumothorax. Their diagnosis is often delayed. Pulmonary endometric lesions, however, often detected in patients with hemothorax and hemoptysis, may be absent in a pro-portion of cases of pneumothorax. The typical presentation of CP includes signs and symptoms of pneumothorax, which occur along with menstruation, most commonly around 24 hours before and 48–72 hours after its onset. However, they may not occur during every menstrual cycle. Suggestive CP lesions on conventional radiography (RTG) include pneumoperitoneum accompanying right-sided pneumothorax, lung opacities, pleural effusion, and nodular infiltrates. Chest and abdomen computed tomography (CT), particularly contrast-enhanced, may additionally show pneumoperitoneum and diaphragmatic lesions. The management of CP includes supportive treatment of acute symptoms and causal treatment to prevent recurrent disease. The article pre-sents the pathophysiology of CP, an overview of diagnostic methods and current therapeutic approaches.
