title: Eosinophils in the cerebrospinal fluid.
abstract: Eosinophils in the cerebrospinal fluid are an uncommon finding that is most often the result of a helminthic infection of the central nervous system. Information from the recorded literature suggests the differential diagnosis of this clinical observation is relatively limited. Therefore, in the appropriate clinical circumstances, cryptic cases of central nervous system disease might be resolved or the diagnostic possibilities at least narrowed by finding these cells in the cerebrospinal fluid.
