Meningoradiculitis post-COVID-19 mRNA vaccination: A case report

Abstract

We present a rare case of meningoradiculitis occurring after mRNA COVID-19 vaccination.This patient, with a history of inflammatory arthritis following rubella vaccination, presented to the emergency department 4 days after her vaccination with both central and radicular nervous system symptoms. Symptoms included pain, sensory and motor deficits in L5 roots distribution, along with signs of central irritation, such as headache, difficulty concentrating and a Babinski sign. MRI showed bilateral L5 nerve roots enhancement. Lumbar puncture showed elevated protein and IgG, and relevant serologies excluded common causes. Prednisone and physical therapy helped the patient to achieve near complete recovery nine weeks after presentation.We concluded that this patient presented meningoradiculitis probably secondary to her vaccination in a context of possible overactive immune system. While such presentations might be rare, and do not constitute a general reason to abstain from vaccination, they must be well recognized and treated.
