[Angiographic features of alveolar soft-part sarcoma]

The angiographic findings were analyzed in five patients with alveolar soft-part sarcoma. The angiographic appearance of the tumors was the same in all five cases: hypervascularity of the tumor including encasement, dilatation, tortuosity and displacement of feeding arteries, remarkable tumor stain and early venous filling. These angiographic findings are considered to be characteristic of alveolar soft-part sarcoma in the differential diagnosis of hypervascular soft tissue mass.
