An autopsy case of intimal sarcoma of the abdominal aorta with bone metastasis and lymph node metastasis: A case report and review of the Japanese literature

Abstract

A 73-year-old man complained of sternoclavicular joint pain; blood tests revealed elevated C-reactive protein. The patient developed delirium; magnetic resonance imaging showed metastatic bone tumors. He died two weeks after admission. Autopsy revealed abdominal aortic intimal sarcoma with metastasis to the peritracheal lymph nodes and sternum. Peripheral arterial embolism and bone metastasis are common symptoms of aortic intimal sarcoma, which implies a place for aortic intimal sarcoma in differential diagnoses of embolism or bone tumors of unknown origin.
