Aortic intimal sarcoma: an unusual case with pulmonary vasculature involvement.

A disseminated intravascular tumour, presenting initially with splenic and small bowel infarction, caused both clinical and histological diagnostic difficulty. At subsequent autopsy the main tumour mass was identified within the aorta. Dissemination of this tumour was confirmed histologically and lectin and immunohistochemical staining performed. On the basis of the clinical and pathological features, we believe this represents a further case of aortic intimal sarcoma.
