Ischemic Stroke in the Course of COVID-19 in a 16-Year-Old Boy

The SARS-CoV-2 virus that causes COVID-19 disease is still evolving and, despite the end of the acute phase of the pandemic, still poses a risk to public health. One of the very rare complications, occurring in less than 1% of children, is multisystem inflammatory syndrome in children (MISC). Due to the risk of thromboembolic complications as well as cardiac problems, MISC carries a number of life-threatening complications. We report a case of a 16-year-old boy who was hospitalized due to general weakness, fever, conjunctivitis, vomiting and diarrhoea. In view of the mother's positive result of the SARS-CoV-2 test, the teenager underwent numerous laboratory tests. Taking into account the critical condition of the patient, anticoagulant and antipyretic treatment, steroids and IVIG were added. During hospitalisation, alarming symptoms occurred, including dysarthria, drooping corner of the mouth and muscle weakness on the right side. The magnetic resonance imaging showed changes characteristic of ischemic stroke. Further studies are needed to assess possible thrombotic complications in children after SARS-CoV-2 infection, and specialists should be more vigilant in paediatric patients presenting with such symptoms.
