Abstract
Arteriography proved useful in evaluation of 17 patients with peripheral soft tissue hamangiomas (15 benign, 2 malignant) by defining their extent, degree of vascularity and source of vascular supply and allowing differentiation from arteriovenous malformations. In 11 cases (all benign), moderate fine caliber hypervascularity with some degree of staining was seen. In 6 (4 benign, 2 malignant) there was marked hypervascularity with coarse, irregular vessels. The course of fine hypervascularity which characterizes most benign hemangiomas closely resembles that seen in malignant soft tissue tumors and may preclude correct diagnosis by angiography alone. Peripheral hemangiomas frequently exhibit distinctive clinical features which when combined with the arteriographic findings enable the radiologist to identify the lesion.
