They can be found along the entirety of the neuroaxis, but pediatric ependymomas are most commonly found in the posterior fossa.\n                    <jats:sup>1<\/jats:sup>\n                    We provide videographic\n                    <jats:sup>2<\/jats:sup>\n                    description of an anatomic approach to the foramen of Luschka in a pediatric patient through a redo suboccipital craniotomy. In this surgical video, we present a 5-yr-old patient with previously resected ependymoma with recurrence in the foramen of Luschka. The patient underwent microsurgical gross total resection of the ependymoma by using a suboccipital approach. He tolerated the surgery well with an uneventful postoperative course followed by radiation therapy. Regardless of molecular subgroup, numerous studies have shown that near or gross total surgical resection followed by radiation therapy provides the greatest progression-free survival.\n                    <jats:sup>1,3\u20136<\/jats:sup>\n                    Ependymomas of the posterior fossa, particularly recurrences or second look resections, can present a challenge to the surgeon because of scarred tissue and precarious location along the brainstem and cranial nerves. Although it has been our institution's observation that these tumors are often debulked, it has been our experience that with an appropriate approach by anatomic dissection, near and gross total resections can be achieved safely and confidently by the surgeon and thus maximize the patient's potential for progression-free survival. The legal guardian of the patient in the presented operative case has given consent for publication of this operative video, and the patient's family provided consent to the procedure.\n                  <\/jats:p>","DOI":"10.1227\/ons.0000000000000023","type":"journal-article","created":{"date-parts":[[2021,12,15]],"date-time":"2021-12-15T13:01:35Z","timestamp":1639573295000},"page":"e51-e51","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Suboccipital Microsurgical Resection of Pediatric Ependymoma in the Foramen of Luschka: 2-Dimensional Operative Video"],"prefix":"10.1227","volume":"22","author":[{"given":"Kara A.","family":"Parikh","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, University of Tennessee Health Science Center, Memphis, Tennessee, USA;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas E.","family":"Merchant","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University of Tennessee Health Science Center, Memphis, Tennessee, USA;"},{"name":"Department of Radiation Oncology, St. Jude Children's Research Hospital, Memphis, Tennessee, USA;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Frederick A.","family":"Boop","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University of Tennessee Health Science Center, Memphis, Tennessee, USA;"},{"name":"Department of Radiation Oncology, St. Jude Children's Research Hospital, Memphis, Tennessee, USA;"},{"name":"Le Bonheur Neuroscience Institute, Le Bonheur Children's Hospital, Memphis, Tennessee, USA;"},{"name":"Semmes Murphey Clinic, Memphis, Tennessee, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2021,11,29]]},"reference":[{"issue":"1","key":"R1-20250821","doi-asserted-by":"crossref","first-page":"93","DOI":"10.1186\/s40880-016-0155-6","article-title":"Treatment implications of posterior fossa ependymoma subgroups","volume":"35","author":"Ramaswamy","year":"2016","journal-title":"Chin J Cancer."},{"issue":"10","key":"R3-20250821","doi-asserted-by":"crossref","first-page":"1319","DOI":"10.1093\/neuonc\/noz069","article-title":"Molecular grouping and outcomes of young children with newly diagnosed ependymoma treated on the multi-institutional SJYC07 trial","volume":"21","author":"Upadhyaya","year":"2019","journal-title":"Neuro Oncol."},{"issue":"2","key":"R4-20250821","doi-asserted-by":"crossref","first-page":"143","DOI":"10.1016\/j.ccr.2011.07.007","article-title":"Delineation of two clinically and molecularly distinct subgroups of posterior fossa ependymoma","volume":"20","author":"Witt","year":"2011","journal-title":"Cancer Cell."},{"issue":"13","key":"R5-20250821","doi-asserted-by":"crossref","first-page":"2570","DOI":"10.1002\/cncr.30623","article-title":"Progression-free survival of children with localized ependymoma treated with intensity-modulated radiation therapy or proton-beam radiation therapy","volume":"123","author":"Sato","year":"2017","journal-title":"Cancer."},{"issue":"2","key":"R6-20250821","doi-asserted-by":"crossref","first-page":"507","DOI":"10.1016\/j.ijrobp.2017.10.002","article-title":"Outcomes after reirradiation for recurrent pediatric intracranial ependymoma","volume":"100","author":"Tsang","year":"2017","journal-title":"Int J Radiat Oncol."}],"container-title":["Operative Neurosurgery"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ovid.com\/10.1227\/ONS.0000000000000023","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,7]],"date-time":"2026-08-07T17:02:19Z","timestamp":1786122139000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ovid.com\/10.1227\/ONS.0000000000000023"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,11,29]]},"references-count":5,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2022]]}},"URL":"https:\/\/doi.org\/10.1227\/ons.0000000000000023","relation":{},"ISSN":["2332-4252","2332-4260"],"issn-type":[{"value":"2332-4252","type":"print"},{"value":"2332-4260","type":"electronic"}],"subject":[],"published":{"date-parts":[[2021,11,29]]},"assertion":[{"value":"2021-04-27","name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2021-08-18","name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}}]}}
