Abstract:
A 32-year-old woman with a history of dilation and curettage for missed abortion at 31 years old had sudden hemoptysis during menstruation on May 25, 1993. She had catamenial hemoptysis again, and was admitted to our hospital on July 21, 1993. After admission, catamenial hemoptysis occurred, and a nodular shadow was noted in the right S4 area on chest roentgenogram and computed tomogram. A few days after menstruation, hemoptysis and the abnormal shadow on chest roentgenogram disappeared. Pulmonary endometriosis was diagnosed by clinical course, past history, and chest roentgenographic findings. During the next menstruation, hemoptysis and a nodular shadow in the right S4 area on chest roentgenogram recurred, so transbronchial lung biopsy and laparoscopy were done. TBLB specimens revealed macrophages with phagocytosed hemosiderin, and laparoscopy revealed pelvic endometriosis. She was treated with buserelin acetate. Catamenial hemoptysis and the nodular shadow on the chest roentgenogram disappeared after treatment.
