Abstract
- We report a case of mature cystic teratoma of the anterior mediastinum that ruptured into the pulmonary artery requiring an emergent surgical treatment. A 39-year-old woman presented an episode of massive hemoptysis and treated with bronchial artery embolization (BAE). On the 10th day after BAE, however, she developed sudden massive hemoptysis and had a deteriorated mental status. For a definitive treatment, she underwent the left pneumonectomy and the tumor resection in the anterior mediastinum. On histologic examination, the tumor disclosed cystic structures composed of mature squamous epithelium, pilosebaceous glands, mature fat tissue, cartilage and bone tissue. Also, there was intrapulmonary hemorrhage due to left pulmonary artery invasion of the tumor.
