What kind of tumor is lower density than renal parenchyma?
Lesions that appear lower density than the renal parenchyma include renal cystic lesions, focal pyelonephritis, abscess, and papillary RCC; in such cases, where clinical history is not informative or may be confounding, MRI may aid in further differentiating among these benign and malignant diagnoses (Fig. 3).

When do hypoechoic masses appear in the uterus?
Uterus. They show up as hypoechoic masses on an ultrasound. These benign tumors may occur in almost 70 percent of women by the age of 50. Fibroids are solid masses that are normally made up of fibrous connective tissue and smooth muscle. Most women with fibroids will have more than one.
What makes a tumor a heterogeneous mass?
All of these different and varying cells make the tumor itself heterogeneous and difficult to treat. Drug administration, one treatment option for cancer, does not kill all the different kinds of cancerous cells in a tumor.
More than 20 percent of adults have a benign liver hypoechoic mass. They can occur in a healthy liver and may not cause symptoms. Some benign types are: A cluster of hypoechoic masses in the liver may be caused by cancer that has spread from another part of the body.
