title: Neurological manifestations of gnathostomiasis.
abstract: Neurological features of 24 patients with nervous system gnathostomiasis were reviewed. The commonest presenting features were radiculomyelitis or radiculomyelitis terminating with encephalitis, and subarachnoid haemorrhage. A primary encephalitic form was noted in 2 patients. The salient feature of the disease was a sudden onset of extremely severe radicular pain and/or headache followed by paralysis of the extremities and/or the cranial nerves. Migration signs were also the hallmark of nervous system gnathostomiasis. No single area of the nervous system was inaccessible to the highly invasive gnathostome lava. Multiplicity and/or rapid progress of lesions beyond the degree of cerebral oedema could only be explained by further migration of the parasite. Death occurred in 6 patients from direct extensive involvement of vital centres in the brain stem or from complications such as pneumonia or septicaemia. Multiple cranial nerve palsies were usually bad prognostic signs.
