Figure 1. Submucosal, intramural, and subserosal leiomyomas in a 43-year-old woman. Axial T2-weighted fast spin-echo (SE) MR image shows submucosal (large *), intramural (small *), intracavitary (straight arrow), and subserosal (curved arrow) leiomyomas. The latter manifested as a suspected adnexal mass at both rectal examination and an outside ultrasonographic (US) examination. MR imaging was requested to exclude an ovarian neoplasm. The left ovary was identified on other images (not shown).
