Neurological Complications in MIS-C: Case Report

Abstract

COVID-19 has seriously affected children and the whole world. Pediatric multi-system inflammatory syndrome (MIS-C), a new syndrome that has not been known before, has been described. Although MIS-C may progress with different clinical manifestations in children, neurological involvement is reported relatively rarely. A 12-year-old girl with cerebral palsy and motor mental retardation was admitted to the emergency department with complaints of cough, fever, mouth sores and malnutrition. As a result of the evaluation, the patient was hospitalized to investigate the etiology of the fever and empirical antibiotic treatment was started, and she developed a rash on the 3rd day and tonic-clonic convulsions on the 5th day. The patient was hospitalized in the pediatric intensive care unit (PICU), and COVID-19 IgG and IgM were positive. Cerebral imaging of the patient was reported as normal. The patient with fever, rash, convulsions lasting longer than five days, and compatible laboratory results were diagnosed with MIS-C. Intravenous immunoglobulin (IVIG) and methylprednisolone treatments were started, and the patient was discharged on the 14th day of hospitalization, whose condition improved. This case is presented as an example of the rare neurological involvement of MIS-C. Detailed clinical investigation and neurological examination are required to exclude neurological sequelae of COVID-19 during the pandemic. The development of general guidelines that can combine them would be instructive.
