Krukenberg tumors are rare cases of metastatic ovarian tumors. Generally, they are bilateral and 70% originate in the stomach, but they can also originate in other organs. They are normally found in young women, on average at 45 years of age, and normally present symptoms due to ovarian involvement: abdominal pain, bloating, nonspecific gastrointestinal symptoms or ascites with malignant cells. They can also be asymptomatic. The diagnosis of the primary tumor can be made before surgery, during further investigations, or during the months following operative surgery. CT and MRI allow the diagnosis and the follow up. The best exam is surely the PET-CT to evaluate an extension (metastasis). Post-surgical and post-therapeutic monitoring is provided by these images. The primary tumor is often too small to be detected and diagnosis depends on meticulous radioscopic and endoscopic exploration. They're usually found in young women. Our two cases imposed a difficult discovery but a good survival for both.
