A representative case of benign breast lesion: sclerosing mastopathy (in a 53-year-old patient). (A) Axial diffusion-weighted MRI map. The lesion shows as an oval mass with a circumscribed margin. (B) Axial apparent diffusion coefficient (ADC) imaging (b value is 800 s/mm²): The ADC of the lesion is 1.96 × 10⁻³ mm²/s. (C) Micrograph with H & E stain (original magnification, 200×). The lobule of the mammary gland displays adenomatoid hyperplasia and extensive fibrous stroma and demonstrates pseudoinvasion.
