title: Angiographic features of malignant fibrous histiocytomas.
abstract: The angiographic findings in 2 cases of metastatic fibrous histiocytoma are discussed. A lesion in the brain was completely avascular and displaced the surrounding vessels, whereas the renal lesions were hypovascular, usually well demarcated, sometimes exhibited beak formation, and demonstrated fine, corkscrew-like tumor vessels with delayed emptying but no tumor blush or early draining veins.
