Simultaneous Arterial and Venous Brain Infarctions in a Patient with COVID-19.

Abstract Introduction: Stroke is one of the manifestations of COVID-19 associated coagulopathy. Arterial infarcts are the most common presentation, however involvement of both arterial and venous irrigation is possible but rare. We report, what is, to our knowledge, the second case of concomitant arterial and venous brain thrombosis evidenced in magnetic resonance. Case presentation: A 62-year-old man presented with acute weakness of the left hand and lack of coordination in the left arm. Nine days earlier, he was positive for SARS-CoV-2 RT-PCR. The brain images revealed two subacute infarcts, one corresponding to the territory of the right middle cerebral artery, and the other in the right frontal cortical vein. Conclusion: The existence of both venous and arterial brain infarcts due to COVID-19 infection, has been previously reported once. Most of the cases of stroke are due to only arterial thrombosis, therefore this could be the starting point to start collecting data about simultaneous compromise in order to assess and compare outcomes, severity of the disease, among other variables.
