Abstract

We present the computed tomography, ultrasonographic findings of a case of contralateral supraclavicular lymphadenopathy that occurred after AstraZeneca COVID-19 vaccination. Contralateral supraclavicular lymphadenopathy is very rare, but may be expected as an adverse reaction after COVID-19 vaccination. Radiologists as well as referring clinicians should be aware of this self-limiting process and its imaging features.

Keywords: COVID-19; Computed tomography; Lymphadenopathy; Ultrasonography; Vaccines.

61-y-old male patient with right supraclavicular lymphadenopathy that developed 5 d after first dose of AstraZeneca COVID-19 vaccine in left arm. A, B. Axial and coronal enhanced neck CT performed 21 d after vaccination demonstrated multiple enlarged, clustered lymph nodes with perinodal infiltration (arrows) in the right supraclavicular area. C. Ultrasonography performed 4 wk after vaccination showed several enlarged oval lymph nodes (arrows) with asymmetric cortical thickening, preserved fatty hilum and mild perinodal infiltration. The extent of lymphadenopathy had decreased, relative to the initial neck CT.
