Fat is a fundamental contrast agent in pelvic imaging. The features of fat are typical on CT and MRI but vary on ultrasonography according to the physical characteristics and histology. The study of pelvic fat is of great importance in pelvic exploration because fat outlines both the normal structures and their borders. Involvement or masking of the pelvic fat is a good marker of carcinologic spread. Changes in pelvic fat may also be observe in inflammatory diseases. Specific diseases of fatty pelvic connective tissue such as lipomatosis and liposarcomas, are classically described. Teratomas with a fatty component derived from pelvic structures (ovaries) are easily diagnosed using imaging methods.
