The global coronavirus disease 2019 (COVID-19) pandemic appears to have some streaks of severity in pediatrics These streaks include variable signs of respiratory distress, a new entity called multisystem inflammatory syndrome, and some evidences of neurological symptoms involving both central and peripheral nervous systems Here, we described the first pediatric patient with COVID-19 who presented with acute transverse myelitis An 11-year-old otherwise healthy girl presented to our clinic with acute onset of lower limbs paresis, urinary and fecal retention, alongside epigastric pain, and fever for 3 days A neurological examination revealed a severe flaccid paraplegia in her lower limbs associated with a sensory level at T5 She was evaluated systematically for all probable causes of her symptoms, and finally, due to having a positive nasopharyngeal PCR test, she was considered to suffer from post-COVID-19 transverse myelitis She underwent intravenous-immunoglobulin, methylprednisolone pulse, and other supportive cares without obvious results Therefore, she underwent seven sessions of plasma exchange with little effects on muscle strength The focal inflammation and injury of the spinal cord, otherwise known as transverse myelitis, have a wide array of potential etiologies Transverse myelitis has been well documented to be the result of viral and bacterial infections We believe our patient was not involved in a cytokine storm status due to good CRP, IL-6 and Ferritin levels Albeit, we cannot certainly consider the patient to have a direct viral impact or involved in a late immunity process To our knowledge, this is the first report of TM in the field of pediatrics occurred after COVID-19 Thus, this is critical to note that children can present with some severe types of COVID-19
