Borderline tumors of the ovary: CT and MRI features and tumor markers in differentiation from stage I disease

OBJECTIVE. We sought to describe MDCT and MRI features and tumor marker levels that differentiate borderline ovarian tumors from stage I ovarian tumors. CONCLUSION. Borderline ovarian tumors are complex masses with imaging features similar to stage I tumors. The thickness of septations and the size of solid components are significantly larger in stage I tumors, and these features may be helpful for predicting likelihood of invasive tumors. However, neither feature allows confident differentiation of borderline tumors from stage I disease.
