Kohler A Chofflon M Sztajzel R Magistris MR 1999 Cerebrospinal fluid (CSF) is rarely analyzed in peripheral facial palsy, and reports in the literature are scarce. We report the CSF findings in 265 patients with acute isolated peripheral facial palsy. The CSF findings were abnormal in 11% of 230 patients with idiopathic peripheral facial palsy, in 60% of 17 patients with Ramsay Hunt syndrome (pleocytosis), in 25% of 8 patients with Lyme disease, in all of 8 patients with HIV infection, and in 2 other patients (sarcoidosis and herpes simplex). We conclude from this large series that the CSF is usually normal in idiopathic peripheral facial palsy. If the CSF is abnormal, a specific cause should be sought. https://sonar.ch/global/documents/230341 eng info:eu-repo/semantics/altIdentifier/doi/10.1007/s004150050328 info:eu-repo/semantics/altIdentifier/pmid/10323312 Journal of neurology. - 1999 Adolescent Adult Aged Facial Paralysis Female HIV Infections Humans Lyme Disease Male Middle Aged Parkinson Disease Retrospective Studies Cerebrospinal fluid in acute peripheral facial palsy. http://purl.org/coar/resource_type/c_6501
