• Abstract: Catamenial pneumothorax is defined as a spontaneous recurrent pneumothorax that occurs in women of reproductive age in a time course related to menstruation.   Catamenial pneumothorax is a challenge for the physician to diagnose and treat due to the infrequency of its occurrence and insufficient understanding of the possible risk factors. In this report, we describe a case of a 42-year-old patient who had an atypical presentation with pleural effusion and not pneumothorax. The patient was submitted to an oophorectomy, and in the postoperative period she developed dyspnea on moderate effort and sporadic episodes of orthopnea. The most interesting factor in this case report is the fact that the patient presented with several episodes of pleural effusion and not pneumothorax, the literature reports that spontaneous pneumothorax is the most common clinical manifestation of thoracic endometriosis, occurring in 72-73% of patients, followed by catamenial hemoptysis, catamenial hemothorax and endometriotic thoracic nodules.
