RESUMO
Magnetic resonance imaging is an important tool in the evaluation of patients with seizures. Frequently, abnormalities are found that lead to further, invasive testing. The first child with transient abnormal findings on magnetic resonance imaging during a time of frequent partial seizures is presented. This lesion disappeared with seizure control. The imaging literature is reviewed concerning transient findings on any imaging modality during frequent seizures. Caution in recommending invasive procedures is suggested when abnormalities are found on magnetic resonance imaging during frequent seizures.

Fifty-nine patients had arteriography because of episodes of amaurosis fugax. Only one third of them had atherosclerotic lesions potentially treatable by carotid endarterectomy. Another third had normal arteriograms, some of these had migraine, heart disease or platelet disorders presumed to be the cause of their symptoms. Patients with amaurosis fugax are a heterogeneous group, and their visual symptoms should not be considered a specific indicator of stenosis of the internal carotid artery.
