But that could change if you get pregnant. hyaline degeneration is demonstrated as low T2 signal intensity, cystic degeneration, which is an advanced stage of intratumoral edema, also shows high signal intensity on T2 weighted images and does not enhance, variable enhancement is seen with contrast administration, the marked high signal intensity with gradual enhancement (albeit mild) suggests, rarely invasion of adjacent venous channels leading to, rarely (0.1-0.5%), they undergo malignant degeneration into. For most women, uterine fibroids don’t cause problems. AJR Am J Roentgenol. Commonly an incidental finding on imaging, they rarely cause a diagnostic dilemma.

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. Lippincott Williams & Wilkins. Any fibroid may undergo atrophy, internal hemorrhage, fibrosis, and calcification. They are commonly multiple (~85% 8), and range significantly in size.

Imaging indicated massive free fluid and a large partially solid uterine mass. in extremely rare instances, lesions capable of metastasizing without malignant transformation: fibroids may torse, leading to acute pelvic pain, pregnancy may cause fibroid growth by 30%. Kawakami S, Togashi K, Konishi I et-al. Areas of calcification can appear as signal voids.
