We report on a patient with refractory epilepsy due to a BOSD, successfully resected with the aid of a multimodal surgical approach using neuronavigation based on MRI and PET, intraoperative ultrasound (iUS) and electrocorticography (ECoG) using depth electrodes. The lesion could be visualized on iUS showing an increase in echogenicity at the grey-white matter junction. IUS demonstrated the position of the depth electrode in relation to the lesion. Depth electrode recording showed almost continuous spiking. Thus, intraoperative imaging and electrophysiology helped confirm the exact location of the lesion. Post-resection ultrasound demonstrated the extent of the resection and depth electrode recording did not show any epileptiform activity. Thus, both techniques helped assess completeness of resection. The patient has been seizure free since surgery. Using a multimodal approach including iUS and ECoG is a helpful adjunct in surgery for BOSD and may improve seizure outcome. | URI: | https://ahro.austin.org.au/austinjspui/handle/1/16970 | DOI: | 10.1016/j.jocn.2017.10.045 | Journal: | Journal of Clinical Neuroscience | PubMed URL: | https://pubmed.ncbi.nlm.nih.gov/29137921 | Type: | Journal Article | Subjects: | Bottom-of-sulcus dysplasia Depth electrodes Electrocorticography Focal cortical dysplasia Intraoperative ultrasound |
