MRI plays an essential role in patients before treatment for uterine mesenchymal malignancies. Burn PR, McCall JM, Chinn RJ, Vashisht A, Smith JR, Healy JC. Fibroid degeneration takes place when the fibroid has been increasing in size over a number of years, and its blood supply is no longer adequate to support the center of the tumor.

Red degeneration of leiomyoma (RDL) is believed to be caused by sudden venous obstruction of the leiomyoma and is often associated with pregnancy or the use of contraceptive drugs [].The name “red degeneration” has been well known among radiologists since its appearance on magnetic resonance imaging (MRI) was first described in 1994 [], but it is virtually unknown to … Bildgebung MRI Typical signal characteristics of a leiomyoma with hyaline or calcific degeneration are difficult to distinguish from non-degenerated fibroids on pelvic MRI.

Transvaginal ultrasound (TVS) is the initial imaging study of choice. Differential diagnosis of a malignancy should be considered in women presenting with a uterine mass, particularly if they are postmenopausal.6 One to two in 1000 women with uterine masses are estimated to have a uterine malignancy.7 Suspicion for malignancy is raised for rapidly growing fibroids, particularly in postmenopausal women who are not on hormone replacement therapy, and women responding poorly to gonadotrophin releasing hormone (GnRH) agonists. AJR 1992;159:555-58. Usually first identified with USG, they can be further characterized with MRI.

The most common type of degeneration is hyaline; it accounts for approximately 60% of all degeneration and produces a low SI on T2WI, without contrast enhancement. Occasionally, atypical features such ad oedema, cystic or hyaline degeneration, and variant subtypes (accounting for 1%) of leiomyomas result in increased T2-weighted signal intensity and therefore pose a diagnostic challenge. The large anterior fibroid could be mistaken for a malignant mass, and is likely undergoing some degree of degeneration (hyaline is most common). Abdom Imaging 2005;30:120-3.
