[The evaluation of angiographic features in the diagnosis of poorly vascularised renal lesions--part II (author's transl)].
Problems arise in the diagnosis of poorly vascularised lesions of the kidney in about 5% of angiograms. Particularly serious is the misdiagnosis of a poorly vascularised malignant lesions as a benign tumour. The value of various angiographic appearances has been assessed in a series of problem cases consisting of 50 malignant and 50 benign lesions. It was confirmed that there is no individual sign which is exclusive to either of these categories. An attempt was also made to judge the value of various signs in this differentiation. An appreciation of the lack of specificity of the various appearances is quite as important as an understanding of their relative significance in the diagnosis of poorly vascularised renal lesions.
