Fibroids Fibroids occur in approximately 25% of women of reproductive age ( Fig. 28-14A , Fig. 28-14B , and Fig. 28-14C ). They consist of nodules of myometrium and typically cause an enlarged uterus with multiple masses that are echo-attenuating. They are sensitive to estrogen stimulation and therefore increase in size during pregnancy. (16) Cystic areas are secondary to degeneration. Clumps of calcification cause echogenic foci with shading. Fibroids are described by their location: they can be submucosal, intramural, subserosal, or pedunculated (see Fig. 28-8A and Fig. 28-8B ). Cervical and broad ligament fibroids are rare. Findings in patients with fibroids are summarized in (Table 28-11). Figure - 28-14a. Fibroids. Transabdominal view of a fibroid uterus.
