New reports show a prevalence of COVID-related thyroiditis. Recent studies suggest that there may be a higher risk of thyroiditis in the setting of SARS-CoV-2, and several cases of Graves’ disease have been reported in individuals with SARS-CoV-2, although the incidence of such findings and their relationship to COVID-19 is unknown. In this report, we present Graves’ hyperthyroidism in a 48-year-old African American male who was admitted to the hospital for complaints of cough, fatigue, and palpitations. He tested positive for SARS-CoV-2 and was found to have suppressed thyroid-stimulating hormone (TSH) and an elevated free T4. The patient had no prior history of thyroid disease. Initially, it was thought to be a case of viral thyroiditis, and he was discharged on prednisone. However, he was found to have positive thyroid-stimulating immunoglobulin (TSI) and a diffuse increase in flow on doppler ultrasound of the thyroid. Subsequently, he was started on anti-thyroid medications with significant improvement. What is unique about this case is that, unlike other described cases in the literature where there was a relapse of a known Graves' disease after COVID-19 disease, our patient did not have a history or symptoms of thyroid disease prior to this event, which should raise the concern about possible activation of Graves' disease after SARS-CoV-2 infection through an autoimmune pathway. In our opinion, physicians, particularly endocrinologists, must be aware of this condition and keep it in mind as a potential differential diagnosis when encountering a similar clinical scenario.en-USAttribution 4.0 InternationalThyrotoxicosisAutoimmunityThyroidSars covid2Covid-19Graves’ diseaseArticle
