Epilepsy in patients with brain metastases triggered by intravenous contrast medium.
187 patients with histologically proven primary neoplasms underwent computed tomography (CT) of the brain following intravenous administration of contrast medium. Eight developed focal epileptic seizures 2 to 4 minutes after the start of the injection. In three of these patients, in whom there was CT evidence of bilateral mass lesions of the brain, this epileptic activity became generalised into grand mal seizures, and two died in status epilepticus. In the other five patients with unilateral deposits in the brain, the focal fits corresponded to the site of the lesion shown by CT. Three of the patients had follow-up electroencephalography (EEG) examinations which showed unilateral focal activity, and their EEG foci correlated with the CT findings.
