Complications of metrizamide myelography.
Adverse neurobehavioral reactions have not been emphasized as a complication of metrizamide myelography. We encountered six such reactions in approximately 250 metrizamide myelograms. All reactions followed either cervical myelography or panmyelography via lumbar puncture. We also treated a single case of tonic-clonic seizure after intracranial spill of metrizamide in a patient without a history of seizure disorder, and a case of myoclonus following a thoracic metrizamide myelogram that showed a highgrade block. Metrizamide should not be used if an intrathecal block is suspected, or if the location to be studied makes intracranial spill difficult to avoid.
