Neurognathostomiasis may be associated with subarachnoid hemorrhage (SAH).
Patient selection: clinical and imaging evidence of subarachnoid hemorrhage
Reasons to consider neurognathostomiasis as the cause of subarachnoid hemorrhage (SAH):
(1) nontraumatic SAH in a child
(2) SAH in a person living or traveling to a region endemic for gnathostomiasis (Southeast Asia)
(3) SAH in a patient with a history of gnathostomiasis
(4) normal cerebral angiography
(5) eosinophilia in blood and/or cerebrospinal fluid
(6) an elevated ratio of CSF to plasma glucose
The diagnosis can be made by serologic testing or PCR.
