Eosinophilia in the Cerebrospinal Fluid of Children with Shunts Implanted for the Treatment of Internal Hydrocephalus
The silicon rubber used for the production of shunts in surgical treatment of internal hydrocephalus is tolerated by the patients. Nevertheless, changes in the cell count of CSF including eosinophilia have been reported after shunt implication. We investigated 615 ventricle and 35 lumbar fluids collected from 404 children after the implantation of shunts for cell count, total protein, albumin, glucose, IgG, IgA and chloride levels. Eosinophilia was found in the CSF of 26 (6.4%). Eosinophilic granulocytes constituting 1 to 3% of the cell population were found in 24 cases with an excess of 4% observed only in two cases (0.5%) as acomplication of shunt implantation.
