A 37-year-old female was indicated to have a non-mass lesion in her left breast on ultrasonography (US) and visited our outpatient clinic. Mammography showed no findings of masses or microcalcification. Dynamic magnetic resonance imaging (MRI) showed a segmental enhanced lesion consisting of nodular and ring enhancement. A US-assisted vacuumed needle biopsy was performed, and the histological findings revealed sclerosing adenosis and apocrine metaplasia. After 1 year of follow-up, the MRI findings suggested both a benign lesion and ductal carcinoma in situ, and surgical excision was performed. We used a new device to evaluate the surgical margin on MRI. The non-mass lesion was excised according to the device-guided margin under local anesthesia. The histological findings revealed the features of mastopathy. Following excision, MRI showed no residual non-mass lesions, and the shape of the patient's left breast was maintained.
