What are the angiographic features of osteosarcoma and how do they relate to histologic type and differentiation?
What are the angiographic features of osteosarcoma and how do they relate to histologic type and differentiation?
Arteriography is a useful technique for evaluating the vascularity of osteosarcomas, choosing biopsy sites, and determining tumor extension.
Angiographic vascularity patterns may aid biopsy planning in osteosarcoma; Level 5 data leave open prospective validation before practice change.
Arteriography was carried out in 64 cases of pathologically confirmed osteosarcoma to evaluate the angiographic features of this lesion. This investigation proved that a variety of angioarchitectures exist in osteosarcomas, mainly related to the histologic type of tissue as well as the degree of differentiation of a tumor. Fibroblastic and chondroblastic osteosarcomas proved to be less vascular than the osteoblastic type, while the most differentiated tumor appeared to be the least vascular. This technique proved useful in choosing the proper site, or sites, for biopsy as well as for determining the intra- and extraosseous extension of the tumor. Instances were also encountered in which it was of assistance in differentiating osteosarcoma from pathologically similar bone lesions.
