FDG-PET in patients with encephalopathy caused by COVID-19

Takeaway

  • Encephalopathy in patients with COVID-19 may be caused by an immune mechanism, as demonstrated by fluorodeoxyglucose-positron emission tomography (FDG-PET).

Why this matters

  • Neurological symptoms are present in a third of cases of COVID-19, including cerebrovascular disease and encephalopathy.

  • It is suspected that encephalopathy is the result of an immune response from COVID-19; however, the brain metabolic abnormalities have not been studied.
