Eosinophilic Meningitis after Bovine Graft Duraplasty for Arnold-Chiari Malformation Type 1 in a 33-year-old Man

  • 1Department of Laboratory Medicine, Gachon University Gil Medical Center, Incheon, Korea.


Cases of pediatric eosinophilic meningitis following duraplasty with a bovine graft have been reported. These patients recovered following the surgical removal of the dural graft or steroid therapy. Decompression for Chiari malformation is a common procedure in both pediatric and adult neurosurgery. We describe the case of a 33-yr-old male patient with eosinophilic meningitis following Chiari decompression via bovine graft duraplasty. Cerebrospinal fluid (CSF) study showed 49 red blood cells/μL and 129 leukocytes/μL with 17% eosinophils. There was no evidence of infectious disease. To our knowledge, this is the first report of adult eosinophilic meningitis after bovine graft duraplasty in Korea.
