Superficial cerebral CMs were categorized into 4 subtypes based on their cortical location or, if subcortical, proximity to the nearest cerebral surface: convexity, medial, basal, and sylvian. Lobar location was also included for subtyping: frontal, temporal, parietal, and occipital.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>RESULTS<\/jats:title>\n<jats:p>A total of 362 CMs were resected in 346 patients. CM subtypes were as follows: 132 (36.5%) convexity, 78 (21.5%) medial, 72 (19.9%) basal, and 80 (22.1%) sylvian. Frontal CMs were most common (155 [42.8%]), followed by parietal (89 [24.6%]), temporal (87 [24.0%]), and occipital (31 [8.6%]). Of all CMs, 302 (83.4%) were cortical and 60 (16.6%) were subcortical. The mean subcortical depth of deep lesions was 2.97 cm, and the mean lesion volume was 4.68 cm<jats:sup>3<\/jats:sup>. Overall, 228 lesions (63.0%) were resected through a transgyral approach, and 134 (37.0%) were resected through a transsulcal approach. Good outcomes (modified Rankin Scale [mRS] score \u2264 2) were observed in 314 patients (86.7%) and poor outcomes (mRS score &gt; 2) in 25 patients (6.9%), and 23 patients (6.4%) were lost to late follow-up (mean follow-up duration 11.5 months). Relative outcomes were good (unchanged or improved mRS score) in 327 patients (90.3%) and poor (worse or died) in 35 patients (9.7%).<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>CONCLUSIONS<\/jats:title>\n<jats:p>Superficial cerebral CMs were resected through a gyrus or sulcus to open the subarachnoid dissection corridors, traversing the full extent of sulci to deepen the approach and minimize tissue transgression. Transgyral dissection avoids associated arteries but is inherently transgressive, whereas transsulcal dissection preserves cortical tissue and may reduce morbidity. Superficial cerebral CMs occupy the largest territory of the 7 types, and the size and surface complexity of the cerebrum make taxonomic subtyping valuable for clear anatomical description.<\/jats:p>\n<\/jats:sec>","DOI":"10.3171\/2023.9.jns231939","type":"journal-article","created":{"date-parts":[[2024,1,20]],"date-time":"2024-01-20T01:19:16Z","timestamp":1705713556000},"page":"123-137","source":"Crossref","is-referenced-by-count":1,"title":["A taxonomy for superficial cerebral cavernous malformations: subtypes of cortical and subcortical lesions"],"prefix":"10.3171","volume":"141","author":[{"given":"Benjamin K.","family":"Hendricks","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Barrow Neurological Institute, St. Joseph\u2019s Hospital and Medical Center, Phoenix; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lea","family":"Scherschinski","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Barrow Neurological Institute, St. Joseph\u2019s Hospital and Medical Center, Phoenix; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jubran H.","family":"Jubran","sequence":"additional","affiliation":[{"name":"University of Arizona College of Medicine\u2013Phoenix, University of Arizona, Phoenix, Arizona"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Katherine","family":"Karahalios","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Barrow Neurological Institute, St. Joseph\u2019s Hospital and Medical Center, Phoenix; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael D.","family":"Hickman","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Barrow Neurological Institute, St. Joseph\u2019s Hospital and Medical Center, Phoenix; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Danielle","family":"VanBrabant","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Barrow Neurological Institute, St. Joseph\u2019s Hospital and Medical Center, Phoenix; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael T.","family":"Lawton","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Barrow Neurological Institute, St. Joseph\u2019s Hospital and Medical Center, Phoenix; and"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"issue":"2","key":"b1","series-title":"Lancet Neurol","first-page":"166","article-title":"Clinical course of untreated cerebral cavernous malformations: a meta-analysis of individual patient data","volume":"15","author":"Horne MA","year":"2016","unstructured":"Horne MA, Flemming KD, Su IC,  Clinical course of untreated cerebral cavernous malformations: a meta-analysis of individual patient data.
