Multimodality Imaging of Triple Receptor–Negative Tumors With Mammography, Ultrasound, and MRI

Abstract

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.
