Fig. 3From: The independent indicators for differentiating renal cell carcinoma from renal angiomyolipoma by contrast-enhanced ultrasoundA case of renal angiomyolipoma. a CUS revealed a hyper-echoic renal mass located in the lower pole of the right kidney (arrows); b CDFI revealed that there was no blood flow signal in the tumor; c CEUS imaging in the early phase showed slow wash in at the region of the tumor (arrows); d CEUS imaging at peak enhancement revealed homogeneous hypo-enhancement (arrows); e CEUS imaging in the late phase showed slow wash out in the region of the tumor (arrows); f Photomicrograph showed renal angiomyolipoma which contains varying proportion of thick-walled blood vessels, smooth muscle, and fat tissue.
