Imaging of Pediatric Neuro-COVID: What We Learned

Although the overwhelming majority of the coronavirus disease 2019 (COVID-19) cases are encountered in adults, less commonly children succumb to the disease. As of January 2022, among the 3.5 million deaths reported, 0.4% (over 12,300) occurred in children and adolescents under 20 years of age. Out of over 12,300 deaths, 42% was encountered in children aged 0 to 9.[1]

Involvement of the neurological systems was recognized very early in the pandemic and The Global Consortium Study of Neurologic Dysfunction in COVID-19 (GCS-NeuroCOVID) was initiated as a multinational research collaborative in April 2020 to describe the prevalence and outcomes of neurological manifestations of the severe acute respiratory coronavirus 2 or multisystem inflammatory syndrome in children (MIS-C) in adults and children.[2] In an interim analysis of the GCS-NeuroCOVID data, information on 1,493 children was made available, of which 14% were diagnosed with MIS-C. Non-neurological symptoms were generally more common than neurological symptoms in children. In the GCS-NeuroCOVID group, 44% of the children presented with at least one neurological sign or symptom while 12% had two or more.[3] In decreasing frequency, headache (20%), encephalopathy (16%), and seizures (8%) were the most common presentations.[3] Anosmia, ageusia (lack of taste sensation), meningitis/encephalitis, and stroke were less common.

A myriad of neuroimaging manifestations can be encountered in pediatric COVID-19[4] including but not limited to acute demyelinating encephalomyelitis,[5] cerebellitis,[6] stroke,[7] focal cerebral arteriopathy,[8] posterior reversible encephalopathy syndrome,[9] [10] and eversible cerebral vasoconstriction syndrome.[11]

It is important that the imaging specialists and clinicians appraise the diverse imaging manifestations of pediatric neuro-COVID involvement. In this issue of Pediatric Neuroradiology, my esteemed colleagues prepared two articles focusing on the nonvascular and vascular manifestations of pediatric neuro-COVID. Our goal is to share our experience in the imaging of pediatric neuro-COVID with the medical community via image-rich manuscripts. We thank the editorial board of Pediatric Neuroradiology for this opportunity and hope the manuscripts will fulfill our stated goal.
