Fig. 1: Axial CT image shows circumferential thickening of the gastric antrum.
Fig. 2: Axial CT image of the pelvis shows bilateral, predominantly solid, less than 10 cm, ovarian masses (stars). There is small ascites.
- Originally described by Dr. Krukenberg in reference to a rare form of malignant ovarian signet-ring tumor that distinction between primary and metastatic signet-ring tumors from the stomach was difficult
- Differentiation between Krukenberg metastatic signet-ring ovarian tumors vs. primary has implication for management and prognosis. Primary signet-ring ovarian tumors can be treated with resection if found early. Krukenberg tumors are indicative of late-stage disease
- Primarily from gastrointestinal adenocarcinoma (stomach, colon)
- Distinction between primary and metastatic ovarian tumors can be difficult on imaging. There is no reliable, consistent feature that is accurate enough to differentiate the two
- Radiologist may suggest possible Krukenberg metastasis if ovarian lesions are solid, less than 10 cm, involve both ovaries and present late.
