Although the growth of uterine leiomyomas is influenced by estrogens, growth during pregnancy has been documented in only a small fraction of cases. Degeneration or torsion of a pedunculated leiomyoma can cause pain. The cesarean section rate is not increased. Pregnant patients with leiomyomas should be followed with serial ultrasound to document the location, size and growth of the tumors, as well as fetal growth. The majority of pregnancies in women with leiomyomas have good outcomes.
