Transverse
Two lesions were seen on ultrasound at the mastectomy site:
- an ill-defined, irregular, hypoechoic lesion
- a spiculated, hyperechoic lesion with posterior shadowing
Case Discussion
Ultrasound-guided core biopsy of both lesions showed invasive ductal carcinoma.
Hyperechoic cancers are infrequent and reported in fewer than 0.8% of invasive and in situ ductal carcinoma. Interestingly, hyperechoic lesions occur 10 times more frequently in infiltrating lobular carcinoma than infiltrating ductal carcinoma.
