Epstein-Barr virus reactivation-related meningoencephalitis with transverse myelitis in pregnancy.

Key Clinical Message: Consider the differential of Epstein-Barr virus (EBV) reactivation in pregnant women who develop progressive meningoencephalitis and transverse myelitis. EBV nucleic acid amplification should be considered in immunosuppressed patients. Abstract: A 32-year-old G10P6M3K22 pregnant female presented to a regional hospital with progressive severe neurological and behavioral deficits. Magnetic resonance revealed cervical transverse myelitis. Lumbar puncture confirmed Epstein-Barr virus (EBV) DNA on a background of IgG-positive EBV serology. A diagnosis of EBV reactivation-related meningoencephalitis with transverse myelitis in pregnancy was concluded.
