Purpose To evaluate frequency and characteristics of epileptic syndromes associated with cerebral venous angiomas (VAs). Methods All epileptic patients in which magnetic resonance imaging (MRI) showed VAs were studied. The characteristics of the epileptic syndromes and their relationships with VAs were examined. Results Out of nearly 1000 epileptic patients submitted to MRI, 4 presented VAs. All of them had partial seizures, most frequently complex partial, with secondary generalization in 3 of 4. Drug resistance (DR) was observed in 2 of 4. One patienl had a small area of cortical dysplasia near the VA; another had a cutaneous angioma. In 2 of 4 there was no topographic concordance between the VA and the EEC focus. Conclusions VAs are rarely found in epileptic patients, differently from other vascular malformations, in particular cavernomas. Topographic and/or etiological relationships between the VAs and the epileptic syndromes are still undefined. For this reason and since the VA may be the only source of cortical drainage of a cortical area, a possible neurosurgical hypothesis in DR patients should be considered with extreme caution.
