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. 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. 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.

El singulto es una manifestación clínica común, de etiología multifactorial que funciona como un arco reflejo frente a noxas irritativas y es mediado por estimulación simpática. Dentro de las causas se han descrito procesos infecciosos como la neumonía, sin embargo, con una baja representatividad. Presentamos el caso de un hombre de 34 años con diagnóstico de infección por virus de la inmunodeficiencia humana (VIH) en estadio 3 con única manifestación clínica inicial de singulto documentando neumonía adquirida en comunidad como etiología. Este caso destaca la importancia del estudio del singulto especialmente en pacientes en contexto de inmunosupresión ya que en ellos la clínica que subyace un proceso infeccioso no suele ser evidente.

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.
