A 9-year-old spayed female German Shepherd dog with a history of orthopedic disease was presented to the North Carolina State University Veterinary Teaching Hospital for evaluation of recent, progressive, bilateral, hindlimb ataxia. Analysis of cisternal and lumbar cerebrospinal fluid (CSF) samples revealed normal total nucleated cell counts and a mild increase in protein concentration in the lumbar sample. In cytocentrifuged specimens of both CSF samples, aggregates of refractile, angular to irregular, pale blue to colorless, crystalline material were observed in the background. Some of the material appeared birefringent under polarized light. Differentials for the material included contrast agent, epidural anesthetics or other pharmacologic agents, or artifact introduced through sample processing, collection, or handling. Based on investigation of clinical and laboratory processes it was determined that tubes used to collect CSF in the hospital recently had been changed from additive-free glass tubes to silica-coated shatter-resistant plastic tubes (BD Vacutainer Plus serum tubes, silicone-coated, Becton Dickinson). A cytocentrifuged preparation of saline placed in a silica-coated tube contained crystalline material identical to that observed in the CSF samples; saline placed in an additive-free glass tube contained no material. In this case, we document the microscopic appearance of highly concentrated silica particles in cytocentrifuged preparations of CSF and underscore the importance of recognizing and identifying this artifact in cytologic preparations.
