title: Usual and unusual MRI findings of ovarian fibroma: correlation with pathologic findings.
abstract: Ovarian fibromas typically exhibit low signal intensity on T(2)-weighted images, which reflects their abundant fibrocollagenous stroma. However, the mass of larger tumors often demonstrates high signal intensity on T(2)-weighted images, which reflects varied degenerative changes, such as cystic degeneration, edematous change, hemorrhagic infarction, or necrosis caused by torsion and myxomatous change. We illustrate typical and atypical magnetic resonance (MR) imaging findings of ovarian fibromas and correlate them with histopathologic findings.
