Krukenberg Tumors


Axial and coronal-reformatted CT images of a 41-year-old woman shows an enlarged, solid-appearing right ovarian mass (arrows). The left ovary (not shown) is normal. 

Facts:
  • Metastatic tumor to the ovary that contains mucin-secreting, signet ring cells
  • Usually originate from primary tumors of GI tract (most common = colon and stomach)
  • 10% of all ovarian tumors
  • Occur in reproductive age
Imaging:
  • Nonspecific appearance. Can be solid or mixed solid/cystic
  • High suspicion for ovarian metastasis if:
    • Bilateral 
    • Complex-appearing ovarian masses
    • Known GI tract tumor (esp. colon and stomach)
    • MRI showing T1/T2 hyper intensity due to mucin
Our case: Ovarian metastasis from primary gastric cancer.
