|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.|
- 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
- Nonspecific appearance. Can be solid or mixed solid/cystic
- High suspicion for ovarian metastasis if:
- 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.
