Neuro-imaging manifestations of COVID-19: Predilection for PICA infarcts

Abstract

COVID-19 has been an ever-evolving viral pandemic which can cause systemic disturbance especially in some of the critically ill patients. Neurologic or Neuro-imaging manifestations of COVID-19 are being increasingly reported in these patients and mainly consist of ischemic strokes, hypoxic ischemic injury and non-specific encephalopathy. Ischemic strokes as expected more commonly afflict major vascular territories, likely due to accentuated hypercoagulability in these patients. Certain vascular territories may be more susceptible to ischemic infarcts. We observed higher predilection for infarcts in posterior inferior cerebellar artery (PICA). This may represent another peculiarity of this pandemic.
