We present a case of multiple liver prolapse due to endometriotic diaphragmatic defects in a woman with right-sided pneumothorax and bilateral salpingectomy. A 33-yr old female patient was referred with moderate right-sided chest pain during previous 3 days. A right-sided moderate pneumothorax was observed on CT scan. On the diaphragmatic dome some tissue nodules were observed. During VATS liver tissue, protruding into the pleural cavity through the defects in the diaphragm was revealed. Resection of the tendinous portion of the diaphragm was performed. The defect was closed with separate sutures. Total costal pleurectomy was performed. The patient was discharged to the gynecologist for further treatment. After prescription of analogues of GNRH no sign of recurrence was seen. In our case no evidence of pulmonary abnormalities was seen, thus, excluding other ways of air passage to the pleural cavity. The only abnormal place was the diaphragmatic dome. Surprisingly, the patient underwent bilateral tube resection in 2010. CT-scan findings, which were firstly proposed to be of endometriotic origin, revealed during VATS as liver microherniatons.
