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.

對比增強磁共振成像（MRI）被廣泛用於診斷各種良性乳腺病變。這些病變的MRI徵象可以是良性、可疑或類似惡性。為便利患者護理，放射科醫師應熟悉良性乳腺病變的MRI徵象。本文討論常見的良性乳腺病變包括乳腺囊腫、纖維囊性變化、乳腺膿腫、乳腺內淋巴結、脂肪壞死、纖維腺瘤、單發和多發導管內乳頭狀瘤、間質纖維化、實質性疤痕、糖尿乳腺病變、注射乳房成形術的肉芽形成、皮膚病變和類似腫塊的正常解剖變異。
