I recently had a bone scan for bone pain and afterward the doc sent me for a renal ultrasound which on the report said there was a echogenic area mid lateral kidney on the right and on the left was ? cyst with echogenic material and shadow and a twinkle artifact. What are they talking about?
The most characteristic ultrasonographic feature of an angiomyolipoma is its echogenicity; however, angiomyolipomas may also cause acoustic shadowing. The echogenic appearance of the tumor is thought to be related to its fat content and the presence of multiple tissue interfaces within it. However, this appearance in a mass is not pathognomonic for angiomyolipomas; renal cell carcinoma has the same appearance. Ultimately collection of particular cell will show that sign.
