A Case of Transverse Myelitis After Moderna Severe Acute Respiratory Syndrome Coronavirus Vaccination.

Transverse myelitis (TM) is an inflammatory syndrome of the spinal cord that presents with acute-to-subacute neurological deficits. The differential for TM is broad and includes demyelinating, infectious, neoplastic and paraneoplastic, autoimmune, and metabolic/toxic etiologies. With the novel severe acute respiratory syndrome coronavirus pandemic, more commonly referred to as the coronavirus infectious disease of 2019 (COVID-19), there have been increasing reports of neurological complications. In this case report, we describe a novel case of longitudinally-extensive TM associated with the Moderna vaccination.
