Encephalomyeloradiculitis after COVID-19 infection.

A woman in her 20s presented with ascending weakness and paraesthesia along with flu-like symptoms. Neurological examination revealed right facial numbness along V2 distribution and flaccidity in her lower extremities, with a motor power of 0/5 throughout. The T4 sensory level and bilaterally positive Babinski sign were noted. Brain MRI revealed multiple bilateral T2/fluid attenuated inversion recovery hyperintense lesions with central enhancement involving the right trigeminal nerve. Full spine MRI demonstrated long-segment thoracic cord demyelination extending from T1 to T11 and nerve root enhancement. An extensive workup for infectious and autoimmune aetiologies was conducted, which revealed a positive COVID-19 result. The patient was diagnosed with encephalomyeloradiculitis secondary to COVID-19 infection. Encephalomyeloradiculitis is a rare neurological condition associated with various underlying conditions. Understanding the causes and differentiating these conditions is essential for appropriate treatment.
