Posterior reversible encephalopathy syndrome (PRES) is a potential neurological complication of coronavirus disease. In comparison with PRES people who do not have coronavirus infection, PRES people infected with coronavirus may exhibit similar to mildly elevated rates of superimposed hemorrhage. 

A systematic review was carried out for compiling and analyzing brain magnetic resonance imaging (MRI) findings in individuals suffering from SARS-CoV-2 infection and PRES.

Using the terms "COVID-19", "PRES", "SARS-CoV-2", databases like Embase and PubMed were explored for peer-reviewed manuscripts elucidating brain MRI findings in individuals (twenty-one years of age or more) with evidence of coronavirus disease and PRES.

In total, 20 manuscripts were incorporated with descriptions of 30 patients. (average age 57 years). Notably, 80% (24/30) of people needed mechanical ventilation. The percentage of patients exhibiting superimposed foci of hemorrhage and restricted diffusion on brain MRI evaluations, is shown in Table 1:

PRES appears to be a potential neurological complication of coronavirus infection.
