Multimodality imaging of triple receptor-negative tumors with mammography, ultrasound, and MRI.

OBJECTIVE We retrospectively reviewed imaging findings for 44 patients with triple receptor-negative breast carcinomas on mammography, sonography, and MRI to determine the imaging characteristics of triple receptor-negative cancers that may improve diagnosis at the time of presentation. CONCLUSION Despite their large size at presentation, triple receptor-negative cancers may be occult on mammography or sonography and frequently have benign or indeterminate features. MRI identified all triple receptor-negative cancers and showed features that had a high positive predictive value for malignancy.
