A lipoma is a benign tumor composed of encapsulated adipose tissue, interspersed by thin septa of fibrous tissue.They are generally classified as either pure or mixed lipomas,depending on the presence or absence of muscle and fibrous tissue. Most uterine lipomas are found in postmenopausal women between the ages of 50 and 70 years. They often present with symptoms similar to uterine fibroids including chronic pelvic discomfort, heaviness, or pressure. Approximately 50%have associated uterine bleeding. Many, however, are asymptomatic. Most ,approximately 88%, arise in either the anterior or posterior walls of the uterine corpus, and most)approximately 60%) are intramural. The remainders are divided equally between a submucosal and subserosal location. Many uterine lipomas are found in association with uterine leiomyomas.These tumors are usually round or oval in configuration and are pale yellow when pure. They generally measure 5-10 cm in diameter. A thin, fibrous capsule may be present. Sonographically ,the highly echogenic central region corresponds to the fatty tissue with the hypoechoic rim thought to correspond to the myometrium incorporated into the growing tumor. Because of the fatty nature of the tumor, CT can be diagnostic when the tumor’s location within the uterus is apparent. Those mixed lesions with predominantly Ieiomyomatous elements may appear identical to uterine fibroids.
