Comprehensive epilepsy evaluation suggested that the epileptic foci involved the whole left frontal lobe but provided less evidence of structural abnormality. To estimate the extent of functional deterioration likely to be caused by an extended left frontal lobectomy, the authors evaluated segmented cortical function in the ipsi- and contralateral hemispheres by the superselective infusion of propofol into the branches of the intracranial artery. The results revealed bilateral and asymmetrical localization of language function because the patient presented with different components of aphasia in each hemisphere. Based on the authors\u2019 assessment of her functional tolerance, an extended left frontal lobectomy was performed and resulted in neurological deficits within the anticipated range.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>LESSONS<\/jats:title>\n                    <jats:p>An accurate understanding of the correlations between vascular and functional anatomy and the highly specific evaluation of language function provides more advanced presurgical assessment, allowing more tailored planning of cortical resection.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3171\/case23451","type":"journal-article","created":{"date-parts":[[2023,12,25]],"date-time":"2023-12-25T18:52:27Z","timestamp":1703530347000},"source":"Crossref","is-referenced-by-count":3,"title":["Bilateral and asymmetrical localization of language function identified by the superselective infusion of propofol in an epilepsy patient with a mild malformation of cortical development: illustrative case"],"prefix":"10.3171","volume":"6","author":[{"given":"Mayuko","family":"Otomo","sequence":"first","affiliation":[{"name":"Departments of Neurosurgery,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shin-ichiro","family":"Osawa","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kyoko","family":"Suzuki","sequence":"additional","affiliation":[{"name":"Behavioral Neurology and Cognitive Neuroscience"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazuo","family":"Kakinuma","sequence":"additional","affiliation":[{"name":"Behavioral Neurology and Cognitive Neuroscience"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazushi","family":"Ukishiro","sequence":"additional","affiliation":[{"name":"Epileptology, and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroyoshi","family":"Suzuki","sequence":"additional","affiliation":[{"name":"Department of Pathology, Sendai Medical Center, Sendai, Miyagi, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kuniyasu","family":"Niizuma","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery,"},{"name":"Department of Neurosurgical Engineering and Translational Neuroscience, Graduate School of Biomedical Engineering, Tohoku University, Sendai, Miyagi, Japan; and"},{"name":"Neurosurgical Engineering and Translational Neuroscience, Tohoku University Graduate School of Medicine, Sendai, Miyagi, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Norio","family":"Narita","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Kesennuma City Hospital, Kesennuma, Miyagi, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nobukazu","family":"Nakasato","sequence":"additional","affiliation":[{"name":"Epileptology, and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Teiji","family":"Tominaga","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery,"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"issue":"3","key":"b1","series-title":"Physiol Rev","first-page":"1181","article-title":"Revisiting the functional anatomy of the human brain: toward a meta-networking theory of cerebral functions","volume":"100","author":"Herbet G","year":"2020","unstructured":"Herbet G, Duffau H.
