Incidental Diagnosis of Ovarian Torsion Due to a Krukenberg Tumor Originating from Gastric Cancer: A Case Report

Background: Benign lesions cause ovarian torsion more commonly than malignant ovarian tumors. Further, Krukenberg tumors have rarely been reported to cause ovarian torsion. Case Presentation: Herein, we present the case of a patient with an incidentally discovered ovarian mass, which was finally diagnosed as a Krukenberg tumor accompanying ovarian torsion with primary stomach cancer. We further review the clinical, imaging, and histological features of Krukenberg tumors. Conclusion: Radiologists should be aware of Krukenberg tumors that may present with ovarian torsion.
