Subacute thyroiditis associated with COVID-19 infection: Two case reports

Abstract

Subacute thyroiditis (SAT) is granulomatous thyroiditis of the thyroid gland that usually occurs after a viral infection. Coronavirus disease-2019 (COVID-19) infection has led to a pandemic that has affected the whole world since late 2019. The virus has been reported to cause different extra-pulmonary clinical symptoms. Few cases in the literature have reported SAT after COVID-19 viral infection. In this ar-ticle, 2 cases were diagnosed, where SAT was presented after COVID-19 infection. Using these cases, we aimed to emphasize that patients who present with pain and tender-ness in the anterior neck region after COVID-19 infection may develop SAT, whose diagnosis can be missed.
