Transverse Myelitis: A Case-Based Discussion of Infectious Etiologies

Transverse myelitis (TM) is a frequently encountered inpatient neurological condition, usually with a broad differential of etiologies narrowed down by detailed history, temporal profile of symptom evolution, and pertinent diagnostic studies. We report a rare case of a 39-year-old man who presented with subacute onset of headaches and confusion, and three days later developed quadriplegia and areflexia. He was diagnosed with acute longitudinally extensive transverse myelitis (LETM) related to Epstein-Barr virus (EBV) superimposed on an initial presentation of streptococcal meningitis. As both etiologies are under-reported, we compare our case to the few similar cases in the literature to guide discussion of the clinical and radiologic findings of parainfectious TM related to EBV and streptococcal meningitis. Readers will have the challenge of attributing our patient's myelitis to one of these parainfectious sources and are encouraged to evaluate for rare infectious etiologies in acute settings.
