Post-COVID-19 Multisystem Inflammatory Syndrome-Related Cerebral Infarction in a Pediatric Patient Managed with Decompressive Craniectomy.

INTRODUCTION

Most people who are infected with the novel severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) are asymptomatic or present with mild upper respiratory symptoms. This is especially true in the pediatric population; however, rarely, a massive cytokine storm can develop, causing multisystem inflammatory syndrome associated with COVID (MIS-C). Furthermore, children may also suffer from acute ischemic strokes secondary to SARS-CoV-2 infection.

CASE PRESENTATION: Here, we present a 2-year-old male who was admitted to the hospital with MIS-C and evidence of a previous SARS-CoV-2 infection. On postadmission day 2, the patient was in cardiogenic shock, had acute kidney injury, liver dysfunction, and metabolic acidosis. He had concurrent altered mental status, and his computed tomography scan showed ischemic infarcts in the territory of the right middle cerebral artery and superior cerebellar artery bilaterally. Magnetic resonance angiography confirmed occlusion of the right middle cerebral artery and right superior cerebellar artery. He underwent an emergent decompressive craniectomy due to rapid deterioration and cerebral edema. After the procedure, he continued to improve and was discharged with moderate disability that improved during outpatient rehab.

CONCLUSION

Though rare in children, SARS-CoV-2 can lead to AIS, especially in the presence of underlying risk factors such as MIS-C and hypercoagulopathy. AIS can be associated with severe mortality and morbidity; however, even in this severe case of AIS, the patient was successfully treated with a decompressive craniectomy.
