✦ Synopsis

Angiography was performed in 19 cases of pathologically confirmed chondromatous tissue tumors. These tumors, due to their specific intercellular nutrition via diffusion, are relatively less vascular than osteoid and fibrous tissue tumors. All benign chondromatous tumors revealed normal angiographic features. In cases of chondrosarcomas, there was a variety of angioarchitecture, ranging from normal to increased vascularity. Heterogeneous vascularity was seen in the majority of hypervascular chondrosarcomas and was related to the cell composition of the tumor. There is a close relationship between the number of vessels in a tumor and its degree of clinical and histopathologic malignancy. The most vascular part of a tumor is the least differentiated and should be used for biopsies. Angiography can be used for the grading of chondrosarcomas, and probably for assessing the clinical prognosis.
