Аннотация
The purpose of this study was to evaluate the frequency and characteristics of epilepsy associated with cerebral venous angiomas (VA). We examined epileptic patients in which magnetic resonance imaging (MRI) showed VA. The characteristics of epilepsy and its relationships to VA were studied. Out of 1020 epileptic patients submitted to MRI in a 10-year period, 4 presented with VA. All had partial seizures, most frequently complex partial, with secondary generalizations in 3. Drug resistance was observed in 2. One patient had a small area of cortical dysplasia near the VA; another had a cutaneous angioma. In 2 patients, there was no topographic concordance between the VA and the focus on electroencephalography. Our study reveals that VA are rarely found in epileptic patients, differently from other vascular malformations, in particular cavernomas. Topographic and/or etiological relationships between VA and epilepsy are still undefined.
