Abstract
 
Introduction: Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was declared a pandemic by the World Health Organization in March 2020. It binds to the ACE-2 receptor and transmembrane serine protease 2 and is highly virulent. There are many sequelae of this virus, including neurological consequences. We have performed a literature review of the neurological sequelae of COVID-19 with relation to neuroimaging and then present a case series.

Case Series: Seven cases were seen by neurology consultants at the Hospital for Special Surgery in New York City between February and May of 2020; 5 met the criteria. The majority of these consultations were called for encephalopathy. Some had neuroimaging of brain MRI or head CT, which all showed microvascular disease. One case had prior imaging without microvascular disease.

Summary/Conclusion: It is known that vascular disease is a risk factor for severe COVID-19 infection. This case series demonstrates the presence of microvascular disease in patients with encephalopathy. We know that microvascular disease can be a risk factor for toxic metabolic encephalopathy. It is unclear if the microvascular disease was present prior to infection, although at least one patient had prior imaging without microvascular disease. More research is needed to determine if COVID-19 infection can cause vascular disease.
