Contrast-enhanced magnetic resonance imaging (MRI) is widely used for diagnosing various benign breast lesions. Such lesions can exhibit benign or suspicious MRI features, and may mimic malignancy. To facilitate patient care, radiologists should familiarise themselves with MRI features of benign breast lesions. This study discusses common benign breast lesions including breast cyst, fibrocystic change, breast abscess, intramammary lymph node, fat necrosis, fibroadenoma, solitary and multiple intraductal papillomas, stromal fibrosis, parenchymal scar, diabetic mastopathy, injection mammoplasty with granuloma formation, cutaneous lesion, and normal anatomic variant mimicking a mass.
