Abstract

Uterine tumor resembling ovarian sex-cord tumor is a very rare uterine neoplasm that was first described by Clement and Scully in 1976. Since then, approximately 70 cases have been reported. However, these case reports have mainly described and discussed the pathologic and clinical features, and few radiologic findings have been presented. We experienced a case of a uterine tumor resembling ovarian sex-cord tumor, which was considered a uterine leiomyoma or leiomyosarcoma upon initial impression at preoperative evaluation including transvaginal ultrasonography and pelvic magnetic resonance imaging. Its diagnosis was pathologically confirmed after total abdominal hysterectomy.

  Fig. 1 Uterine tumor resembling ovarian sex-cord tumor in a 50-year-old woman. Trans-vaginal ultrasonography (A) shows an approximately 8 × 7 cm, round, solid mass with internal multi-loculated anechoic cystic portions (arrow) in the anterior wall of the uterus. Pelvic magnetic resonance imaging (B-G) shows an approximately 8.7 cm, round, solid mass in the right anterolateral wall of the uterus. On T1-weighted image (B), the mass shows iso-signal intensity compared to the myometrium. Its solid portion shows high signal intensity and its cystic portion shows bright signal intensity on T2-weighted images (C, D). Gadolinium-enhanced T1-weighted images (E) show mild enhancement except for the cystic portions. There is slight diffusion restriction in the solid portion of the mass on diffusion-weighted images (F, b = 1000) and the ADC map (G). Microscopic findings (H) of a uterine tumor resembling ovarian sex-cord tumor. Microfollicular, macrofollicular, and glandular architectural patterns are identified (hematoxylin & eosin stain, ×200).
