There are no MRI findings associated with [disease name]. However, a MRI may be helpful in the diagnosis of complications of [disease name], which include [complication 1], [complication 2], and [complication 3].
MRI
- MRI may be helpful in the diagnosis of Sexcord/ stromal ovarian tumors[1][2][3][4][5]
- 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 intratumoral 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
