Case Report


A 37-year-old woman experienced repeated catamenial hemoptysis. She had a history of intrauterine curettage. Computed tomography (CT) showed ground glass opacity (GGO) in the right upper lung lobe. We suspected pulmonary endometriosis and scheduled surgery coincides with her menstrual cycle. Then she underwent surgical resection after pre-operative CT-guided marking of the pulmonary endometrial lesion. A yellowish change of the pleura was observed near the marking and the lesion was resected using video-assisted thoracoscopic surgery. Histopathologically, endometrial glands and intimal interstitium were evident. She has no symptoms 2.5 years after surgery. In this case, scheduling the surgery at the time of her menstrual period and video-assisted thoracoscopic surgery (VATS) after CT-guided marking facilitated effective resection.
