Acute Post-Myelographic Meningitis with Iohexol

We report a case of severe chemical meningitis complicating iohexol myelography. Cerebrospinal fluid findings include a white blood cell count of 1700(94% polymorphouse cell, 6% lymphocyte ), sugar 20mg/dl and p rotein 170mg/dl. Chemical meningitis can not be distinguished from acute bacterial meningitis on the basis of the clinical findings and cerebrospinal fluid examination. A cerebrospinal fluid gram stain and culture were the only reliable test in deciding the etiology of the meningitis. The authors report this rare complication from iohexol myelography with review of pe rtinent literature.
