Overview
There are no MRI findings associated with [disease name].
OR
[Location] MRI may be helpful in the diagnosis of [disease name]. Findings on MRI suggestive of/diagnostic of [disease name] include [finding 1], [finding 2], and [finding 3].
OR
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]
- 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
