Fig. 1. Case no 1. A 72 years old female presented with a left sided breast and axillary pain 5 days after receiving the first dose of AstraZeneca vaccine.

Axillary ultrasonography showed a lymph node with an intact fatty hilum, but with a uniformly thickened nodal cortex measuring > 3 mm. This was deemed indeterminate in appearance and therefore a follow up ultrasound scan was performed.
