Breast MRI of contralateral breast cancer

Breast MRI can be used to diagnose contralateral disease in newly diagnosed breast cancer patients. This series depicts a patient with right breast cancer detected on mammography.

(A) Architectural distortion (arrow) was detected in the right breast on screening mammography.

(B) Ultrasound demonstrated a solid mass on the right and biopsy under ultrasound-guidance confirmed invasive ductal carcinoma.

(C) Preoperative MRI confirmed the biopsy clip within the proven cancer in the right breast.

(D) MRI also showed a suspicious lesion in the left breast that was not seen on mammography.
