Abstract Objective: To evaluate the value in localizing the epileptic focus by magnetic source imaging(MSI) in patients with cavernous angioma(CA) and seizure. Methods: MRI and MSI examination were proceeded in 13 patients with CA and had epilepsy. To observe the relationship of epileptic focus determined by MSI with the location of the CA, all of the 13 patients were operated on. Results: The distance of the location between the epileptic focus identified by MSI and the CA was less than 2cm in 11 cases and more than 2cm in 2 cases. According to Engel classification of epilepsy, all the patients achieved Engel Class 1 outcomes. In 12 cases was seizure free for 6~53 months after operation. One patient had only 1 seizure episode after operation. Conclusion: MSI could define the relationship between the epileptic focus and the location of the CA. The results of MSI have much value to make the surgical plan before operation.
