[Role of color flow mapping ultrasonography in the study of renal tumors].
Tumors cm. 3 in diameter or less have revealed a high frequency of hyperecoic sonographic features mimicking angio-myolipoma. C.T. can confirm the presence of intralesion fat useful to exclude a potentially curable renal cell carcinoma. CFM and duplex ultra sonography can depict a peri and intra lesion neovascularization in small renal cell carcinoma. In the tumor langer than cm. 3 when hyper-vascular CFM and duplex sonography can detect the neovascularized blood vessels surrounding and penetrating the tumors. In the tumor staging the duplex and CFM ultrasonography is useful to demonstrate neoplastic trombosis of renal vein and inferior vena cava.
