Thoracoscopic resection of diaphragmatic lesion of catamenial pneumothorax with elevated level of serum CA125; a case report

Abstract

A 45-year-old woman had experienced repeated episodes of right-sided pneumothorax. The last recurrent pneumothorax occurred after onset of menstruation with elevated serum CA125 level, suggesting catamenial pneumothorax. Thoracoscopy revealed 3 punchout like perforations in the right diaphragm. Partial resection of the diaphragm was performed under VATS. Microscopic findings of the resected diaphragm showed endometrial tissue. Post operation serum CA125 level was normal.
