Echovirus meningomyeloencephalitis with administration of intrathecal immunoglobulin
Abstract:
Echovirus meningomyeloencephalitis was treated with cerebral intraventricular immunoglobulin. This case includes a complete examination of the central nervous system (CNS) supported by viral culture studies, immunoperoxidase staining and electron microscopy. Neuronal loss was most severe in the cerebellum and spinal cord. This may lead to the ataxia and a poliomyelitis-like syndrome often seen in cases of echovirus meningomyeloencephalitis. Focal encephalitic lesions, antigen-antibody reactions and live virus were found at numerous levels of the CNS in spite of intrathecal and intravenous immunoglobulin therapy. This mode of therapy and the electron microscopic features noted in echovirus infections are discussed.
Insights
Echovirus meningomyeloencephalitis caused severe neuronal loss in the CNS, leading to ataxia and polio-like symptoms. Intraventricular immunoglobulin therapy showed limited effectiveness against the virus and associated lesions.
Area of Science:
- Neurology
- Virology
- Immunology
Background:
- Echovirus infections can cause severe central nervous system (CNS) inflammation, including meningomyeloencephalitis.
- Neuronal damage, particularly in the cerebellum and spinal cord, is a hallmark of severe echovirus CNS disease.
- Ataxia and poliomyelitis-like syndromes are common clinical manifestations.
