초록

흉부 대동맥 미분화성 다형성 육종은 매우 드문 질환으로 색전 사례, 신혈관성 고혈압, 등 통증 등의 증상을 보일 수 있다. 특히 대동맥 벽에서 기원하여 소낭 동맥류 파열로 보고된 경우는 극히 드물며 진균성 동맥류나 관통성 죽상경화 궤양과 감별이 어렵다. 이에 저자들은 소낭성 동맥류 파열로 혈관 내 흉부 대동맥 치료를 시행한 후 종괴가 발생하여 수술적 생검으로 확진된 미분화성 다형성 육종의 전산화단층촬영과 양전자방출단층촬영 소견을 보고하고자 하며 이를 통해 정확한 진단과 적절한 치료에 도움을 주고자 한다.

Cases of undifferentiated pleomorphic sarcoma of the thoracic aorta are rare, and usually present with embolic events, renovascular hypertension, or back pain. Mural-based undifferentiated pleomorphic sarcomas that present as ruptured saccular aneurysms are extremely rare and are difficult to differentiate from mycotic aneurysms or penetrating atherosclerotic ulcers. Herein, we report a case of histopathologically proven undifferentiated pleomorphic sarcoma arising from the wall of the descending thoracic aorta that manifested as a mass after thoracic endovascular aortic repair for the treatment of a ruptured saccular aneurysm. We present findings obtained by CT and PET to provide helpful information for the accurate diagnosis and appropriate treatment of future cases.
