A Krukenberg tumour (KT) is an ovarian cancer mainly derived from metastasis of gastrointestinal tract cancers. While the incidence of KT is low, the prognosis is poor. We report a case of a gravida 1, para 0 woman at 36 weeks of gestation who had bilateral, large ovarian masses, virilization, and hirsutism. She had an uneventful spontaneous vaginal delivery and died 12 months postpartum, despite having received a full course of chemotherapy. Obstetricians should pay close attention to any gastrointestinal symptoms that occur during pregnancy, especially in patients presenting with bilateral ovarian tumours, as early diagnosis or detection of KT and primary lesions could significantly improve the prognosis.
