Axillary Adenopathy in Patients with Recent Covid-19 Vaccination: A New Diagnostic Dilemma

Discrimination between Benign and Malignant Post-SARS-CoV-2 Vaccination Lymphadenopathy is Feasible

“…I read with interest the article by Ashoor et al [ 1 ] about three patients who developed axillary lymphadenopathy (ALP), also known as reactive axillary lymph nodes (ALNs). The patients were examined 5 days after the first dose of SARS-CoV-2 vaccination with the AstraZeneca vaccine (patient 1), 27 days after the AstraZeneca vaccine (patient 2), and 1 day after the second dose of the AstraZeneca vaccine (patient 3).…”

“…The patients were examined 5 days after the first dose of SARS-CoV-2 vaccination with the AstraZeneca vaccine (patient 1), 27 days after the AstraZeneca vaccine (patient 2), and 1 day after the second dose of the AstraZeneca vaccine (patient 3). All three patients developed ALP/ALN homolaterally to the injection site [ 1 ]. The study is interesting but raises concerns that need to be discussed.…”

Looking Ahead to 2022 for the Korean Journal of Radiology

“…The rapid shrinkage of research studies on COVID-19 in radiology was because although radiology is a discipline mainly focused on diagnosis, the approach in dealing with the pandemic has shifted from diagnosis to vaccination and treatment/patient management in 2021. The KJR published eight articles related to COVID-19 in 2021 [ 3 4 5 6 7 8 9 ]. This number was much lower than that in 2020 and only two of them concerned the diagnosis of lung disease (commentaries on articles published in 2020) [ 8 9 ].…”

“…This number was much lower than that in 2020 and only two of them concerned the diagnosis of lung disease (commentaries on articles published in 2020) [ 8 9 ]. Other articles involved vaccination-associated lymphadenopathy [ 3 4 ], a meta-analysis of related neuroimaging findings [ 5 ], and modeling for patient management [ 6 7 ]. These topics reflect the phase shift in dealing with the pandemic.…”

“…These topics reflect the phase shift in dealing with the pandemic. Notably, with the population-based large-scale vaccination campaign, COVID-19 vaccine-related lymphadenopathy that mimics malignant lymphadenopathy has become an issue that radiologists should be aware of [ 3 4 ].…”
