Methods From December 2006 to May 2010, 38 cases of pharmacal intractable epilepsy were confirmed through operation and pathologic examination. Among them, there were 25 cases of hippocampal sclerosis, 2 cases of temporal lobe atrophy combined with brain dysplasia, 4 cases of heterotopic gray matter and macrogyria, 3 cases of vascular malformation, 2 cases of glioma, 1 case of cyst in brain, and 1 case of traumatic epilepsy. Video-EEG was applied to monitor the source of epileptoid discharge and the features of brain electrical activity during and between the occurrences of epilepsy. MRI was used to detect the manifestation characteristics of the epilepsy focus, and retrospective analysis was done to compare these findings with operational and pathological results. Results The accuracy rate of Video-EEG in locating the epilepsy focus was 100% (38/38) during the occurrence of epilepsy, and 53% (20/38) between the occurrences of epilepsy. The accuracy rate of MRI in diagnosing the epilepsy focus and relevant abnormalities during the occurrence of epilepsy was 89% (34/38), and 79% (30/38) in characterizing the abnormalities. Conclusion Video-EEG combined with MRI examination is effective in locating and characterizing the epilepsy focus, which can provide more useful information for the surgery in treating pharmacal intractable epilepsy.
