On contrast-enhanced T1-weighted sagittal MR image (836/14), right ovarian mass (arrows) is enhanced as much as ovary, but sharp demarcation between tumor and ovary (arrowheads) is still clearly visible. Borderline epithelial tumors are also known as atypical proliferating tumors and used to be called low malignant potential tumors.These tumors look the same as invasive epithelial ovarian cancers when seen on an ultrasound or CT scan. Borderline papillary serous tumors of the ovary, also known as ovarian tumors of low malignant potential, were first described in 1929 and were designated for separate classification in the early 1970s by the World Health Organization. Like most epithelial ovarian tumors, borderline papillary tumors are derived from serous or mucinous cell types.

Serous borderline tumors (SBTs) are the most common histologic subtype of borderline ovarian tumors. They account for two-thirds to three-quarters of all borderline ovarian tumors. Borderline epithelial ovarian tumors, or tumors of low malignant potential, were first described in 1929. 1 Borderline tumors have an excellent prognosis and are common in woman of childbearing age. Surgical excision with total abdominal hysterectomy and bilateral salpingo-oophorectomy has been the primary treatment, with a trend toward fertility conservation in young women.
