Background
Acute necrotic encephalopathy(ANE) in children is a very rare complication of Severe Acute Respiratory Syndrome Coronavirus 2(SARS-CoV-2) infection, which has rarely been reported worldwide.
Case presentation
A 45-day-old girl was admitted to our hospital with fever and listlessness. A nose swab tested positive for novel coronavirus nucleic acid, and her cerebrospinal fluid was positive for SARS-CoV-2. An early head magnetic resonance imaging (MRI) scan indicated multiple abnormal signals in her bilateral cerebral hemispheres, and encephalitis was diagnosed. Twenty-three days after hospitalization, bilateral cerebral atrophy-like changes were observed by MRI, with multiple softening lesions in the bilateral cerebral hemispheres, accompanied by convulsions. She was admitted to hospital for mechanically-assisted ventilation, and her condition improved after treatment of her symptoms, including anti-epileptic medication, anti-infection drugs, glucocorticoids, and immunoglobulins.
Conclusions
Acute necrotic encephalopathy associated with novel coronavirus infection in children should be detected and treated as early as possible. Satisfactory short-term efficacy can be obtained, but long-term neurological sequelae often linger.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
