Ovarian torsion during pregnancy: a case of malignant ovarian cancer

INTRODUCTION: Ovarian torsion is an acute and emergency condition during pregnancy. It is caused mainly by the benign cystic mass in the ovary. However, ovarian cancer may be seen as a cause which is very rare during pregnancy. Here, we aim to present a case of pregnant women with ovarian torsion and diagnosed with malignant ovarian tumor.
METHODS: A 40 years old 25th week pregnant woman applied to our hospital with a sudden onset of abdominal pain. In the USG examination, a 20X18 cm multilobulated thick septal papillary cyst in the right adnexal area was observed. 10cm free liquid was observed in the abdomen. Since the patient had acute abdominal pain, an operation decision was taken. In the operation, approximately 2 liters of sero-mucinous fluid was observed in the abdomen, and a 20 cm cyst was observed in the right ovary. Right oophorectomy was performed.
RESULTS: The patient was diagnosed with grade 2 moderately differentiated mucinous carcinoma as a result of pathology. She didn't accept the postoperative chemotherapy until the delivery. Delivery was made by cesarean at week 37. Followed by a hysterectomy, unilateral oophorectomy and pelvic-paraaortic lymph node dissection, and apendectomy with omentectomy. The patient had no complications after the operation, was discharged.
DISCUSSION AND CONCLUSION: Although the incidence of ovarian cancer development during pregnancy is low, it should be kept in mind. Ovarian cancer may appear as ovarian torsion during pregnancy. Pregnancies complicated by ovarian cancer should be considered as a high-risk pregnancy and should be approached multidisciplinary
