The novel coronavirus infection SARS-CoV-2 (COVID-19) has gone down in history as one of the deadliest pandemics in history. Since the first reports of SARS-CoV-2 infection, a lot of data has appeared regarding the features of the COVID-19 pathogenesis and the effect of the virus on various organs and tissues. It is known that SARS-CoV-2 can cause both pulmonary and systemic inflammation, causing multiple organ dysfunction. In addition, since the beginning of the pandemic, reports of the relationship between COVID-19 and thyroid dysfunction have continued to emerge. Numerous studies have demonstrated that the thyroid gland and the entire hypothalamus-pituitary-thyroid axis can be significant targets for the pathogenic effects of SARS-CoV-2.The classic thyroid dysfunctions in infectious diseases, also described in COVID-19, are subacute thyroiditis and secondary hypothyroidism. Of particular interest is the development of atypical thyroiditis-SARS-CoV-2 against the background of COVID-19, a condition first recorded during COVID-19, associated with formidable cardiovascular complications and high mortality in patients with COVID-19, not previously encountered in other viral infections.This article describes a clinical case of SARS-CoV-2 atypical thyroiditis in a patient with bilateral viral pneumonia in the acute period of COVID-19.
