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 extrapulmonary clinical symptoms. Few cases in the literature have reported SAT after COVID-19 viral infection. In this article, 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 tenderness in the anterior neck region after COVID-19 infection may develop SAT, whose diagnosis can be missed.
