|Imaging spectrum of non-epithelial ovarian tumors: a road less travelled|
Ovarian cancer represents a heterogeneous group of distinct diseases ( Fig. 1 ). Carcinomas (malignant epithelial tumors) constitute approximately 90% of ovarian cancers. Non-epithelial ovarian tumors accounts for about 10% of all ovarian tumors . They are classified as germ cell tumors and sex-cord stromal tumors of the ovary. Those groups of tumors are seen at a younger age compared to surface epithelial tumors.
Various histological compositions of those tumors cause a wide spectrum of imaging findings. Some of these tumors have characteristic imaging features such as fat signal in mature cystic teratomas. On the other hand, some properties of the tumor such as hemorrhage, cystic degeneration, and low T2 signal intensity may cause pitfalls. Overlapping features with malignant surface epithelial tumors may cause diagnostic challenges.
We aim to review magnetic resonance (MR) imaging features of non-epithelial ovarian tumors using our cohort.
