a Axial T1WI post-contrast, b Post-subtraction imaging: An oval-shaped lesion with homogenous enhancement, c Axial T2WI: The lesion displays low signal intensity, d Axial T2WI FS: The lesion displays high signal, no fat suppression, e Axial STIR: The lesion displays high signal intensity, f kinetic curve: Type I, rising curve, g Axial DWI: The lesion displays high signal intensity, h ADC value = 1.5 × 10⁻³ mm²/s (cut-off value of < 1.21 × 10⁻³ mm²/s), i FA = 0.05 (cut-off value of > 0.15), j RA = 0.10 (cut-off value of > 0.13), k Maximum eigenvalue (λ1) = 2.21 × 10⁻³ mm²/s (cut-off value of < 1.71 × 10⁻³ mm²/s), l Middle eigenvalue (λ2) = 1.39 × 10⁻³ mm²/s (cut-off value of < 1.31 × 10⁻³ mm²/s), m Minimum eigenvalue (λ3) = 1.2 × 10⁻³ mm²/s (cut-off value of < 1.19 × 10⁻³ mm²/s) and n Fiber Tractography: Almost intact fiber tracts, suggesting benign lesion. Provisional diagnosis by DCE-MRI and DTI parameters: Benign lesion. Histopathological diagnosis: Fibroadenoma
