[Pathogen-induced diseases of the spinal cord and adjacent structures].

Pathogen-induced myelitis is an inflammatory disease of the spinal cord that can be caused by various pathogens including viruses, bacteria, fungi or parasites. The most frequent viral pathogens include herpes and enteroviruses, while bacterial myelitis can be caused by, e.g., Mycobacterium tuberculosis, Borrelia burgdorferi and Treponema pallidum. Fungi such as Candida and Aspergillus and parasites such as Toxoplasma gondii and schistosomes can also cause myelitis. The main symptom is subacute paraplegia with motor, sensory and autonomic deficits to varying degrees, often accompanied by fever and a general malaise. Following a thorough clinical examination and review of the medical history diagnostic imaging procedures, such as magnetic resonance imaging (MRI) along with cerebrospinal fluid analysis and blood tests that include antibody testing are warranted. The treatment is directed at the cause of the myelitis and mostly with anti-infective agents but for some viral pathogens no specific treatment is available and the only option is a symptomatic treatment. The prognosis is very variable and depends on the etiology and severity of the disease. A fast diagnosis and targeted treatment are crucial to achieve a good outcome.
