A 52-year-old female presented with a right breast lump. ( A ) The mammograms (craniocaudal and mediolateral oblique views) reveal an irregular mass in the right breast and a small isodense nodule with subtle spiculation in the left breast (red arrows). ( B ) Computed tomography (CT) showed subtle spiculated margins. ( C ) Correlative ultrasound shows an irregular hyperechoic nodule with indistinct margins and posterior acoustic shadowing. Due to suspicious morphological features on mammography and CT, an ultrasound-guided biopsy was performed. Final histopathology revealed invasive lobular carcinoma.
