The guidelines say that if the density of a mass on the kidney is less than 20 Hounsfield units it has a strong likelihood of being a cyst, and that is what most radiologists go by, said Robert G. Uzzo, MD, MBA, FACS, chair of the Department of Surgical Oncology at Fox Chase. A kidney lesion is a generic term to describe an area of kidney tissue that deviates from normal, healthy tissue.
