[Critical analysis of the arteriography of primary malignant tumors of the bones, on the occasion of 19 unedited cases].

From the analysis of a series of 62 unedited cases of arteriography of osseous tumors including 19 primary malignant tumors, it was confirmed that the majority of angiographic signs described as being characteristic of malignant tumors of the bones are not significant. They are found in benign tumors and in ordinary inflammatory phenomena: several cases of osteoid osteoma, myeloplax tumor or simply of osseous reconstruction permit one to make criticisms. On the other hand, one must endeavour to demonstrate, by means of a technique whose main elements are recalled, vascular abnormalities which are the only typical ones and which furthermore are found in "silent" tumors such as chondrosarcomas or fibrosarcomas. These vascular abnormalities are given in detail, and several examples of them are given.
