Figure 2:

Images in a 60-year-old woman with no personal or family history of breast cancer who presented for routine screening mammography 9 weeks after COVID-19 vaccination in her left arm. (A) Mediolateral oblique and (B) craniocaudal mammographic views of the left breast demonstrate a new spiculated mass in the left breast (dotted arrows). In addition, a left axillary lymph node (solid arrow in A) had increased in prominence and density in comparison with that seen on her prior mammogram. (C) US scan shows a lymph node with eccentric cortical thickening measuring 6 mm (arrow) in the left axilla. (D) US-guided core biopsy of lymph node yielded metastatic carcinoma.
