Concomitant Guillain-Barré Syndrome and Acute Transverse Myelitis in an Older Adult-A Case Report.

PURPOSE: Guillain-Barre syndrome concomitant with spinal cord involvement, which is defined as Guillain-Barre syndrome and acute transverse myelitis overlap syndrome, is rarely seen in the elders. Here we present a 68-year-old female patient who developed Guillain-Barre syndrome, as well as acute transverse myelitis at the same episode. CASE REPORT: This patient developed acute weakness of lower limbs, which then rapidly became tetraplegia and hyporeflexia within 5 days. She also had impaired pinprick and vibration sensations below T4, as well as urinary and defecation incontinence. The nerve conduction studies revealed a motorsensory axonal neuropathy. Cerebrospinal fluid analysis showed albuminocytological dissociation and elevated IgG index. The spinal magnetic resonance imaging study revealed heterogeneously contrastenhanced, long-segmental intramedullary lesion from C2 to T3. Other laboratory findings, including blood anti-aquaporin 4 antibody, were not remarkable. The patient's tetraplegia was gradually improved by plasmapheresis and methylprednisolone pulse therapy. CONCLUSION: Although Guillain-Barre syndrome and acute transverse myelitis overlap syndrome is occasionally seen in young adults, it could still occur in the elderly patients. Plasmapheresis and steroid pulse therapy could be beneficial to improve functional outcome of patients with this immunemediated neurological disease.
