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.
