case_images: Magnetic resonance imaging revealed bilateral multiloculated ovarian tumors (left: 125 x 88 mm; right: 50 x 35 mm) with intracystic papillary projections (Figure 1).
case_images: Photographs of the left ovary showing a multinodular mass with multiple intracystic nodules.

case_images: Consequently, she underwent FSS, which included a left salpingo-oophorectomy, resection of the right ovarian tumor, and samplings of the peritoneum and omentum (Figure 2).
case_images: Histological analysis of the left ovarian mass showed epithelial proliferation and atypia without stromal invasion (arrowheads) (H&E staining).

case_images: Examination of permanent histopathological specimens confirmed the bilateral ovarian tumors as serous BOTs (Figure 3).
case_images: T2-weighted magnetic resonance imaging scan (transverse section) showing right ovarian tumor, suggesting the recurrence of serous borderline tumor (arrowheads).

case_images: Subsequent laparotomy confirmed the presence of serous BOT, interpreted as a recurrence (Figure 4).
