Arterial floating mural thrombi are a characteristic imaging pattern in SARS-CoV-2-related ischemic stroke

Floating arterial mural thrombi attached to atherosclerotic plaques are unique characteristic source of AIS in SARS-CoV-2 patients. They may lead to ischemic stroke in patients with mild or asymptomatic infection up to 1-2 weeks from SARS-CoV-2 diagnosis. Patients with embolic AIS and SARS-CoV-2 diagnosis should perform high resolution cranio-cervical vascular imaging to evaluate floating thrombi as a potential embolic source.
