Magnetic Resonance Imaging/cerebrospinal Fluid-negative Myelitis Following COVID-19 with a Dramatic Response to Early Aggressive Immunosuppressive Therapy.

ABSTRACT

A 57-year-old man presented with subacute-onset paraparesis, bilateral dysesthesia in his lower extremities, and bladder/bowel disturbance six weeks after being infected with severe acute respiratory syndrome coronavirus 2 infection [coronavirus disease 2019 (COVID-19)]. A neurological examination suggested transverse myelitis at the level of the lower thoracic spinal cord. However, repeated spinal magnetic resonance imaging (MRI) showed no abnormalities in the spinal cord. Laboratory and cerebrospinal fluid (CSF) tests ruled out other etiologies of myelitis, eventually suggesting COVID-19-associated myelitis. Aggressive immunosuppressive therapy, started soon after hospitalization, dramatically improved his symptoms. Early aggressive immunosuppressive therapy should therefore be considered in cases of MRI/CSF-negative myelitis associated with COVID-19.
