We report 23 women with axillary adenopathy on breast imaging after recent coronavirus disease (COVID-19) vaccination. A total of 13% were symptomatic (axillary lump), 43% were undergoing screening; and 43% undergoing diagnostic imaging for other reasons. BI-RADS 2 was assigned in one woman, BI-RADS 3 in 21 (ultrasound in 4-24 weeks), and BI-RADS 4 in one. Radiologist familiarity and evidence-based guidelines are needed to avoid follow-up imaging and biopsies for reactive adenopathy after COVID-19 vaccination.
