In this study, we present the ultrasound imaging features of lymph nodes arising in the regional lymph node chain after the first or second dose of the copyright-BioNTech COVID-19 vaccine.Ipsilateral lymphadenopathy adjacent to the vaccine injection site is an extremely rare but expected adverse reaction following COVID-19 vaccination.Although Ski de fond - Accessoires - Fartage axillary lymphadenopathy is more common, cases of supraclavicular lymphadenopathy have also been reported after widespread vaccination against COVID-19.

Ultrasonography examinations were performed on seven patients with no previous pathological conditions, who presented to our radiology department after receiving the copyright-BioNTech COVID-19 vaccine.Bilateral axillary, supraclavicular and subclavicular lymph node stations were explored.These patients Bath Towel Set typically present with enlarged hypoechoic lymph nodes with the loss of fatty hilum, asymmetric or diffuse cortical thickening, and increased hilar and cortical vascularization on the color doppler ultrasonography of the ipsilateral axillary and supraclavicular regions.
