This study highlights two ovarian tumors with functional stroma, one producing testosterone and the other estrogen. Imaging revealed multilocular cystic masses, mimicking other known functioning ovarian tumors.

Area of Science:

  • Gynecologic Oncology
  • Radiology
  • Endocrinology

Background:

  • Ovarian tumors can exhibit hormonal activity due to functional stromal cells.
  • Previous literature primarily documented this phenomenon pathologically.

Observation:

  • Two cases of ovarian tumors with functioning stroma were reported: an ovarian carcinoid producing testosterone and a mucinous cystadenoma with elevated estrogen.
  • Magnetic resonance (MR) imaging demonstrated multilocular cystic masses with variable signal characteristics.

Findings:

  • The imaging features mimicked those of Sertoli-Leydig cell tumors and granulosa cell tumors, both recognized functioning ovarian neoplasms.
  • This represents the first radiological literature report of ovarian tumors with hormonal activity secondary to functional stroma.

Implications:

  • Radiologists should consider functional stroma as a potential cause of hormonal activity in various ovarian tumor types.
  • Enhanced awareness of this association can improve diagnostic accuracy and patient management for functioning ovarian tumors.
