MRI
- MRI may be helpful in the diagnosis of Sexcord/ stromal ovarian tumors[1][2][3][4][5][6][7][8][9][10][11]
- Findings on MRI differ according to the subtypes of tumors
Granulosa cell tumors:
- They show heterogeneous signal intensity on both T1WI and T2WI and high signal intensity on DWI images
- They appear as solid masses, tumors with hemorrhagic or fibrotic changes, multilocular cystic lesions or completely cystic tumors
- Heterogeneity within a solid tumor is caused by intra-tumoral bleeding, infarct or fibrous degeneration

Fibroma, Fibrothecoma, and Thecoma:
- As the name indicates fibromas have abundant collagen and fibrous contents, these tumors show relatively diagnostic imaging findings
- They appear as hypointense masses on T1-weighted MRI with very low signal intensity on T2-weighted imaging
- Dense calcifications are often noted
- Scattered areas of high-signal-intensity in the mass indicate either edema or cystic degeneration

Sclerosing Stromal Tumor of Ovary:
- They show hyperintense cystic components or a heterogeneous solid mass of intermediate to high signal intensity on T2-weighted MRI
- There is clear-cut contrast enhancement with internal small cleft and cysts
- The tumors show early peripheral enhancement with centripetal progression on dynamic contrast-enhanced imaging
- Characteristic early enhancement reflects the cellular areas with their prominent vascular networks, whereas an area of prolonged enhancement in the inner portion of the mass represents the collagenous hypocellular area
