Learning objectives
To review magnetic resonance (MR) imaging features of serous borderline ovarian tumours (SBOT)
To demonstrate tips and tricks for challenging diagnosis of SBOT
To review important mimickers of SBOT.
To review the clinical approach to SBOT including staging,
management,
treatment and follow-up
Background
Borderline ovarian tumours (BOT) account for 15-20% of non-benign ovarian neoplasms [1].
These tumours show low malignant potential with intermediate mitotic activity,
nuclear atypia and lack of obvious invasion of the stroma [2].
They are most commonly serous or mucinous.
About 9-15% of all serous neoplasms are known to be borderline type [2](Figure 1).
Cystic serous tumours with more than 10% BOT architecture are classified as serous BOT according to last WHO classification of ovarian tumours (2014) [3].
Radiological diagnosis of serous borderline tumours is...
Findings and procedure details
We had series of 20 patients (age range 18-72) with pathologically proven SBOT between July 2015 and July 2018.
We demonstrated MR imaging features of SBOTs using our cohort.
Histologically,
typical borderline serous tumours are non-invasive proliferative neoplasms characterized by multiple fibrous papillae with extensive and complex hierarchical branching [2].
Similarly in MR images,
they are usually seen as a cystic or a solid mass showing abundant hyperintense papillary projections with low signal internal branching and ovarian stroma preservation with a hypointense ovarian capsular margin...
Conclusion
SBOTs are intermediate group of neoplasms between benign and malignant ovarian tumours.
Accurate characterization of these tumours is important in surgical planning since fertility-sparing surgery is can be offered to young patients with early-stage disease.
MRI can reveal the complex architecture of SBOT and enable classification into cystic and surface subtypes.
