Ischemic stroke on SARS-CoV2 vasculitis in a healthy young girl.

Background And Aims: In France, we noted the fifth wave of SARS-CoV2 pandemic, characterized by presence of Omicron variant. This variant is very contagious, but less often aggressive, especially in pediatric population.

Methods: We report a case of a 10-year-old girl, previously healthy, not yet vaccinated for SARS-CoV2, presented to our emergency department for left hemiparesis associated with headache and vomiting, without any signs of respiratory tract infection.

Results: Cerebral CT and MRI showed an ischemic stroke of right sylvian artery. Magnetic resonance angiography performed upon resurgence of new symptoms was in favor of vasculitis on the right internal carotid and right sylvian artery. PCR SARS-CoV2 was positive for Omicron variant. She fully recovered after few days and was treated with acetylsalicylic acid and intravenous corticosteroids.

Conclusion: We report this case to raise awareness on the possible complications related to SARS-CoV2 infection and we highly recommend vaccination in this age group.
