Ans- B. Angiomyolipoma
In the given CT image, the renal mass is containing fat content, which is suggestive of angiomyolipoma, which is a fat-containing benign renal neoplasm.
The commonest benign tumors is the angiomyolipoma (hamartoma).
Angiomyolipoma is an unusual tumor of the kidney, often but not always associated with tuberous sclerosis. Its high-fat content has a typical appearance on CT.
Ultrasound demonstrates a well- defined predominantly echogenic mass.
