Complex partial status epilepticus following myelography with metrizamide.

Complex partial status epilepticus developed in two patients following myelography with metrizamide. The status epilepticus was manifested by confusion and complex motor symptoms, and electroencephalograms (EEGs) showed ictal activity alternating independently over both hemisphere. Immediate clinical improvement occurred with antiepileptic treatment, and to date no sequelae have been observed. Neither patient had a previous history of epileptic seizures, but both had preexisting EEG abnormalities.
