Objective:
To describe a patient with recent onset of rapidly progressive virilization who was diagnosed with an androgen-secreting tumor of the left ovary, localized by selective ovarian vein catheterization and hormonal sampling (SOVHS).
Design:
Case report.
Setting:
Tertiary community-based medical center.
Patient(S):
A 32-year-old woman presenting with progressive virilization over a period of 4 months was found to have a Leydig cell tumor of the left ovary.
Intervention(S):
Transvaginal ultrasound of the pelvis, followed by contrast-enhanced computerized tomography of the abdomen and the pelvis. Selective ovarian vein sampling was performed to localize the tumor. Laparoscopic left salpingo-oophorectomy and washings were also performed.
Main Outcome Measure(S):
Initial serum total T levels were 1,505 ng/dL, and the free serum T levels were 234 ng/dL. After SOVHS, the total serum T levels in the left ovarian vein is reported to be 20,967 ng/dL, and in the right ovarian vein, they were reported to be 1,351 ng/dL. Three months after laparoscopic left oophorectomy, the serum total T levels were 11 ng/dL. Institutional review board approval was obtained.
Result(S):
Patient's ovarian tumor removed laparoscopically was reported to be a Leydig cell tumor. Rapid decreases in free and total T followed tumor removal.
Conclusion(S):
Selective ovarian vein catheterization and hormonal sampling is an effective diagnostic modality that can help localize small ovarian tumors.
