PURPOSE: We describe a 52-year-old man with a glioblastoma multiforme who had a prolonged partial seizure immediately after undergoing a computed tomography (CT) scan of the head with intravenous contrast medium. METHODS: Earlier computed tomography (CT) had demonstrated a ring-enhancing hypodense mass. The patient was treated with a regimen of intravenous Tirapazamine and brain irradiation. After CT scan performed on the day of his second hospitalization, the patient became aphasic. EEG showed continuous high-voltage semirhythmic sharp and slow waves in the left posterior temporal and parietal regions consistent with status epilepticus (SE). Intravenous lorazepam and a loading dose of phenytoin were administered. RESULTS: On the next morning, the patient's condition had improved almost to baseline. He had no recurrent seizures. EEG at 2-month follow-up showed no epileptiform discharges. CONCLUSION: This appears to be the first reported case of contrast medium-induced status epilepticus.
