Intimal angiosarcoma of the aorta: report of a case and review of the literature.

Although extremely rare, the group of primary malignant tumors of the aorta (PMTA) exhibits enormous histologic heterogeneity. In most cases, diagnosis is established late in the course of the disease; the median survival time is only a few months. We present the case of a 75-year-old patient with an intimal angiosarcoma of the infrarenal abdominal aorta and discuss the clinical presentation, histopathologic diagnosis, and classification of primary aortic sarcomas. A critical review of the diagnostic and therapeutic management in this case revealed that the atypical aortic thrombus should have prompted a comprehensive preoperative diagnostic work-up, specifically with magnetic resonance tomography of the aorta and bone scintigraphy.
