[The problem of angiographic diagnosis of giant cell tumors (author's transl)]

The value of angiography in the diagnosis of giant cell tumors of the bone was investigated in 12 patients listed in the Viennese bone tumor register. It could be shown that angiographic criteria of malignancy can frequently be found in grade II cell tumors. Therefore angiography does not seem to be helpful in differentiation and prediction of benign and malignant course of giant cell tumors.
