A neurogenic urinary retention workup failed to reveal the aetiology, but a spinal tap incidentally showed occult meningeal reaction with positive oligoclonal band. The patient had no headache, nausea/vomiting or fever. Considering his clinical laboratory findings, his neural lesions seemed to involve the meninges and spinal cord, suggestive of {\textquoteleft}form fruste{\textquoteright} meningitis-retention syndrome. When clinicians encounter patients with urinary retention of undetermined aetiology, a spinal tap should be considered.}, URL = {https://casereports.bmj.com/content/13/11/e236625}, eprint = {https://casereports.bmj.com/content/13/11/e236625.full.pdf}, journal = {BMJ Case Reports CP} }
