Infections of the spinal cord and adjacent structures

Abstract

Inflammation of the spinal cord and the adjacent structures can be caused by viruses, bacteria, fungi and parasites. Viruses predominantly infect the spinal cord and the nerve roots directly or trigger asecondary immune response, whereas bacteria, fungi and parasites tend to form abscesses, granulomas and cysts and can lead to asecondary compression of the spinal cord, similar to adestructive osteomyelitis. The etiological clarification of an acute or subacute spinal process is carried out based on the clinical presentation, the time course of the development of symptoms, the immune status, neuroimaging and microbial and/or molecular biological examinations of cerebrospinal fluid and serum. The tropism of individual pathogens to certain fiber structures and cellular clusters in the spinal cord in synopsis with the clinical presentation, neuroimaging and ahistory of exposure, can often quickly lead to afocused clarification and diagnosis. This article deals with important pathogens of spinal and paraspinal infections, the geographical distribution, the clinical and neuroimaging presentation with special consideration of the anatomical and topographical localization and recent epidemiological developments. Particular attention is paid to the outbreak of poliomyelitis due to circulating vaccine-derived poliovirus (cVDPV).
