Materials and Methods: This study involved five patients with catamenial hemoptysis diagnosed as pulmonary endometriosis. All cases were diagnosed on the basis of bronchoscopic abnormalities. In one patient, endometrial glandular cells were seen on transthoracic fine needle aspiration biopsy. In three, hemoptysis ceased after Danazol treatment. The pattern, location and number of parenchymal abnormalities and the presence or absence of pleural lesion were analyzed retrospectively on plain chest radiographs (n=S) and CT scans(n=S). Follow-up study for each menstrual period was performed in two cases and changes from the initial lesion were assessed. Results : Plain chest radiographic findings showed focal ground-glass opacity in three cases; two were in the right lung and one in the left. CT findings included ground-glass attenuation (n=3) and a mixed pattern of ground-glass attenuations and consolidations(n = 2). Sites were single in four cases, and in one case, there were two; thus there were in all six lesions. Five of these were located in the right lung and subpleural region, continving to the pleura. Pleural lesion was not detected on either chest radiographs or CT scahs. F이low-up CT scans (n=2) showed a similar lesion at the same síte. Conclusion : In patient with repeated catamenial hemoptysis, CT may be helpful for the diagnosis of pulmonary endometriosis by exclusion of other diseases.","source_license":"CC0","license_restricted":false}
