Seizures after myelography with lopamidol

A 32-year-old man presented to the emergency department (ED) with seizures 6 hours after a lumbar myelogram with iopamidol (Isovue-M 200, Squibb, Princeton, NJ). Seizures are a rare complication after myelography with the current nonionic contrast agents and have not been previously reported in the emergency medicine literature. Emergency physicians should be aware of this potential complication because outpatient myelograms are frequently performed, and these patients may present to the ED after seizures.
