To identify benign lesions that share malignant features in imaging findingsTo describe the various causes of benign breast lesions that may mimic carcinoma in imaging findingsTo get to the correct diagnosis and to avoid unnecessary surgical interventionTo be familiar with these benign lesions for more appropriate diagnostic approach
This exhibit aims to do a pictorial review of the imaging findings of carcinoma-mimicking benign breast lesions. These presentation include fatty necrosis, diabetic mastopathy, adenosis, sclerosing adenosis, ruptured inflammed cyst, inflammation with abscess, granulomatous mastitis, fibroadenoma, fibroadenomatous mastopathy, apocrine metaplasia.

Benign breast lesions somtimes have malignant features in imaging and to be familiar with these benign lesions mimicking breast malignancy can be helpful for radiologists to plan appropriate diagnostic approach.
