7. (A) Axial abdominal CT
A complex solid and cystic mass in the right adnexal area, 12.3 cm in size, was found and highly suspected to indicate ovarian metastasis (black arrow).

8. (B) Axial abdominal CT. A complex solid and cystic mass in the left adnexal area, 8.3 cm in size, was found and highly suspected to indicate ovarian metastasis (black arrow).

9. (C) Coronal abdominal CT
(C) Coronal abdominal CT. Complex solid and cystic masses in the bilateral adnexal areas, larger on the right (black arrow), smaller on the left (white arrow), were found and were highly suspected to be ovarian metastases. Hemoperitoneum was noted (arrowhead).

11. Exploratory laparotomy with salpingo-oophorectomy.
(A) A large ruptured right ovarian tumor was found (14.0 × 9.5 × 4.5 cm), along with
(B) a smaller left ovarian tumor (8.5 × 6.5 × 5.0 cm).
Exploratory laparotomy with salpingo-oophorectomy.
2500 ml of blood and ascites and a ruptured right ovarian mass with active intra-abdominal hemorrhage were found.

12. Conclusion: Rupture of a Krukenberg tumor with intra-abdominal hemorrhage or ovarian torsion may present as acute abdomen. Despite its rarity, this diagnosis should be considered in women presenting with acute abdomen and ovarian tumors and hemoperitoneum.
