Contralateral breast cancer (CLB) is the most common second primary breast cancer in patients diagnosed with breast cancer. The majority of patients harbouring CLB tumours develop the invasive disease. Almost all invasive carcinomas are believed to begin as ductal carcinoma in situ (DCIS) lesions. The sensitivity of MRI for DCIS is much higher than that of mammography. Case report. We report the case of a woman who was treated with breast conserving therapy 10 years ago. At that time the invasive medullary carcinoma was diagnosed in the left breast. Ten years later mammographically occult DCIS was diagnosed with MRI-guided core biopsy in contralateral breast. Conclusions. There might be a potential role of MRI screening as part of an annual follow-up for patients diagnosed with breast cancer. %K high-grade DCIS %K second primary breast cancer %K MRI %U http://versita.metapress.com/content/250n8213656r0117/?p=28f69436068d4465b8397578aca28ebe&pi=3
