Diagnosis With Brief Discussion
- Diagnosis
- Pulmonary endometriosis (Catamenial hemoptysis)
- Radiologic Findings
- Chest radiograph shows an air-fluid level containing nodule in Rt basal lung. CT shows a 2.2cm cavitary nodule with surrounding ground glass opacity in the right lower lobe.
Op finding(right lower lobe, wedge resection): subpleural mass with peripheral black pigmentation
- Brief Review
- * Thoracic endometriosis may involve the trachea, bronchi, lung parenchyma, pleura or the diaphragm.
* Pleural and diaphragmatic endometriosis usually causes chest pain and dyspnea, and may be associated with pneumothorax, pleural effusion or hemothorax, whereas the tracheobronchial and parenchymal disease may present with periodic hemoptysis simultaneous with their menses.
* The radiological findings for catamenial hemoptysis are often normal, but they can show single or multiple nodules, thin-walled cavitary lesions, consolidations displaying cyclic changes in size as a presentation of the menstrual hemorrhage in the adjacent alveolar spaces.
