In these lesions, smooth muscle cells are so widely separated by abundant myxoid material that mitotic count and cellularity cannot be assessed precisely (,1,,5,,6). With extensive edema, the entire lesion has high signal intensity on T2-weighted images and demonstrates marked enhancement (,11) (,,,,,,Fig 6). Acute pain occurs in 30 % of women with uterine fibroids, usually due to acute degeneration or torsion of pedunculated subserosal myomas or prolapse of pedunculated submucosal ones. Because of the pressure of the surrounding tissue, the lesion tends to have an irregular rather than rounded configuration. Fibroids with hyaline or calcific degeneration are difficult to distinguish from non- degenerated fibroids … However, leiomyomas can demonstrate various histopathologic patterns of degeneration, some of which alter the MR imaging appearance.
