Learning objectives To depict the main imaging features of borderline ovarian tumours.
Read more Background Ovarian tumours can be benign, malignant or borderline and, based on their cell type, they can be broadly classified into epithelial cell, germ cell, sex cord-stromal, mesenchymal or metastatic tumours. Borderline ovarian tumours (BOT) belong to the epithelial cell type and account for 10-20% of all ovarian neoplasms. They are considered to represent an intermediate phase in the stepwise progression from benign to malignant ovarian cancer and are characterized by increased cell proliferation and nuclear atypia, without frank stromal invasion....
Read more Findings and procedure details Serous Borderline Ovarian TumourSerous BOT is the most common subtype, accounting for up to 70% of all cases. The median age of presentation is 50 years, with one third of patients being younger than 40 years. They can be of two histological subtypes: classic (accounting for 90% of cases) and cribiform / micropapillary. It is thought that most low-grade serous ovarian carcinomas arise from the cribiform / micropapillary subtype, which is thus considered a pre-malignant lesion. Also, it has been...
Read more Conclusion MRI plays an important role in the diagnosis of BOT allowing for a confident diagnosis in the majority of cases, thus permitting a targeted approach to surgery, namely in a fertility-sparing scenario.
