Juvenile Granulosa Cell Tumor as a Cause of Ovarian Torsion Complicating Pregnancy

Abstract

Abstract

Background:

Juvenile granulosa cell tumors (JGCTs) are very rare and have the potential to be malignant. These tumors are often detected as an incidental finding in young girls prior to puberty. Timely diagnosis is often delayed secondary to lack of specific tumor markers or imaging characteristics.

Case:

A 20-year-old woman, gravida 1, para 0, at 22 weeks and 6 days of gestation, presented to labor and delivery triage complaining of severe left lower quadrant pain. The patient was found to have a large pelvic mass that led to ovarian torsion. Surgical resection was remarkable for JGCT.

Results:

Final pathology was remarkable for a 1157-g JGCT of the ovary measuring 19 × 16 × 9 cm with hemorrhagic necrosis consistent with torsion. The remaining hospital course was uneventful, and the patient was discharged to go home on postoperative day 3 in good condition with a viable pregnancy.

Conclusions:

The current authors' case is the only reported case of a JGCT presenting as a cause for ovarian torsion in a pregnant patient. These tumors are often aggressive requiring proper surgical resection and follow-up. When evaluating pregnant patients with adnexal masses requiring surgical intervention, JGCT should be part of the differential diagnosis.
