ABSTRACT
The current COVID-19 pandemic caused by the novel SARS-CoV-2 virus is now recognized to be associated with a coagulopathy that can result in arterial and venous thromboses. In this report, we describe a case of large-vessel cerebrovascular thrombus in a therapeutically anticoagulated 89-year-old male admitted with COVID-19 infection. Despite clinical improvement following COVID-19 pneumonitis, symptoms of an acute left-sided total anterior circulation stroke rapidly developed 10 days after initial COVID-19 symptom onset. Computed tomography angiography imaging confirmed acute large-vessel thrombus in the terminal segment of the internal carotid artery resulting in acute right middle cerebral artery territory infarction. Thromboembolic events in the context of COVID-19 infection have recently been described in critically unwell patients. However, to the best of our knowledge, this is one of the first cases of large-vessel thrombus in a patient with COVID-19 infection receiving concurrent therapeutic anticoagulation.
