Nonconvulsive status epilepticus following metrizamide myelography.
Epileptic seizures are a known complication of metrizamide myelography. To our knowledge, this is the first report of a case of nonconvulsive status epilepticus of the absence type following metrizamide myelography. There was symptomatic and electroencephalographic improvement after intravenous administration of antiepileptic drugs, and there was no neurological residual. Nonconvulsive status epilepticus should be considered when impairment of consciousness supervenes after radiographic procedures using metrizamide.
