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.

폐동맥 내로 파열되어 응급수술이 필요했던 전종격동의 성숙 낭포성 기형종을 경험하였기에 보고하는 바이다. 39세 여자 환자가 대량객혈을 주소로 내원하여 기관지 동맥 색전술을 시행 받았다. 그러나 기관지 동맥 색전술 시행 10일 후 환자는 갑작스런 대량객혈과 함께 의식저하가 생겨 응급 개흉술을 시행하였다. 수술은 좌측 전폐절제술과 전종격동에 있는 종양절제술을 시행하였으며 조직학적 검사 결과 종양은 성숙 상피세포와 피지선, 성숙 지방조직, 연골, 골조직 등으로 구성된 낭포성 구조물로 관찰되었고, 좌 폐동맥으로 침습된 종양의 일부가 파열되어 폐내출혈을 보이고 있었다.
