ABSTRACT
A 55-year-old woman was admitted to our hospital because of gait disturbance and urinary retention that acutely emerged 1 week after severe acute respiratory syndrome coronavirus 2 infection. Acute inflammatory myelopathy was clinically suspected, based on bilateral lower-limb weakness with an extensor plantar response and an elevated immunoglobulin G level in the cerebrospinal fluid. Whole-spine magnetic resonance imaging findings were normal. The central conduction time was extended, based on somatosensory evoked potentials. Her lower-limb weakness was partially ameliorated with immunosuppressive therapy. Postinfectious myelopathy is a rare neurological complication of coronavirus disease 2019 and can develop with normal radiological findings.
