Leiomyomatous Tumors, Uterus

  • Uterine leiomyoma (uterine fibroid) is a benign tumor of myometrial (smooth muscle) origin; it is the most common solid benign uterine neoplasm. Its prevalence increases with age and it is more common in black than in white women. It can be solitary or multiple, with different locations within the uterus: intramural (most common), subserosal, and submucosal, some even being pedunculated.

  • CT: CT imaging is not the investigation of choice for the characterization of pelvic masses. Uterine fibroids are often an incidental finding on CT scans performed for other reasons. The typical finding is an enlarged and irregular uterus or a mass in continuity with the uterus. 4 % of fibroids contain calcifications. Most myomas enhance with contrast similar to normal myometrium.

  • MRI: MRI is the preferred method for accurately characterizing and localizing pelvic masses. Nondegenerated leiomyomas appear isointense to hypointense on T1-weighted images and hypointense on...
