Abstract
Hyperechogenic renal tumors [in humans] were studied to elucidate whether it would be possible to discriminate between malignant and benign tumors with the aid of echo strength and homogeneity of a series of 58 tumors, 42 were malignant (renal carcinomas) and 16 benign (15 angiomyolipomas and 1 hemangioma). Of the malignant tumors, 5% were highly echogenic (the echo strength equal to or higher than that of sinusal area) and 95% moderately echogenic (echostrength higher than that of parenchyma and lower than that of sinusal area), and 12% had homogeneous and 88% nonhomogeneous echo pattern. Of the benign tumors 75% were highly echogenic and 25% moderately echogenic, while 94% were homogeneous and 6% nonhomogeneous. It is not possible to differentiate with absolute reliability between malignant and benign hyperechogenic renal tumors on the basis of the ultrasonographic finding.
