Transverse myelitis in a pediatric patient with COVID-19

ABSTRACT

Case Report Transverse myelitis is the segmental inflammation of the spinal cord with motor and sensory abnormalities at and below the level of the lesion. Often, the etiology is unknown but may be attributed to autoimmune conditions or viruses. Here we describe a rare case of transverse myelitis secondary to severe acute respiratory syndrome coronavirus 2 [SARS-CoV-2]/coronavirus disease (COVID-19). Case A 5-year-old male with a history of asthma presented for vomiting and altered mental status. The patient was noted to be altered, lethargic, and in respiratory distress. Intubation was performed. After family collateral was obtained, it was revealed that patient possibly ingested Sertraline and/or Risperidone at an unknown time prior to arrival. History also revealed that he had slurred speech, ataxia, and a fall with trauma to forehead 1 day prior to arrival. He tested positive for COVID-19 via PCR and chest x-ray revealed RLL consolidation. Dexamethasone was started. When sedation was weaned in hopes of extubation, patient was noted to be alert, but not moving extremities and had minimal gag and cough reflex. MRI of Brain and Spine were conducted and revealed findings suggestive of long segment transverse myelitis involving C2 to C3. LP was performed with unremarkable CSF studies and IV Solumedrol was started. In light of active COVID-19 infection, and worsening respiratory status, patient started on 5 days Remdesivir. Further, patient underwent ten sessions of plasmapheresis. Repeat MRI was consistent with previous. Physical and occupational therapy initiated at the onset of illness in hopes of achieving musculoskeletal improvement. Patient had some minimal musculoskeletal improvement, however, given his condition, decision was made for patient to undergo placement of gastrostomy and tracheostomy tubes. Patient was weaned off of sedatives and withdrawal was treated with a clonidine taper. Once stabilized, patient was transferred to neurological inpatient rehabilitation center. Discussion Neurological manifestations in children affected by SARS-CoV-2 are relatively common but are often non-specific. Worldwide data reports only 1% of children with COVID-19 present with severe symptoms of encephalopathy, seizures, and meningeal signs. Pathophysiology is multifactorial, including direct invasion of the CNS, vascular insufficiency, immune dysregulation and autoimmunity. Imaging is paramount in the diagnosis of transverse myelitis. Treatments are emerging and may include steroids, immunoglobulin, plasmapheresis, and monoclonal antibodies. Conclusion Much is unknown about COVID-19. Information is emerging and evolving daily. Cases of transverse myelitis in COVID-19 have been reported in few adult patients and minimal pediatric patients. Practitioners should keep transverse myelitis on their list of differentials for neurological complications of SARS-CoV-2 infections and initiate aggressive treatment with a multidisciplinary approach.
