Although surgical management has been reported, the diagnostic challenges, differential considerations, and therapeutic strategies remain debated. We report a 5-year-old boy with progressive vomiting, severe headache, gait instability, and incontinence. High-resolution magnetic resonance imaging with T2-CISS sequences confirmed a membranous obstruction at the foramina of Magendie and Luschka. The patient underwent microsurgical fenestration via suboccipital craniotomy, with histopathological confirmation of arachnoid membranes without signs of infection or malignancy. The postoperative course was favorable with complete symptom resolution. Notably, persistent papilledema was observed at 2-month follow-up despite clinical improvement, but showed gradual regression during subsequent visits, underlining the need for cautious postoperative monitoring.<\/jats:p>","DOI":"10.1093\/jscr\/rjag931","type":"journal-article","created":{"date-parts":[[2026,10,19]],"date-time":"2026-10-19T18:55:23Z","timestamp":1792436123000},"source":"Crossref","is-referenced-by-count":0,"title":["Rare presentation of hydrocephalus occlusus caused by membranous obstruction of the foramina of Magendie and Luschka: a case report"],"prefix":"10.1093","volume":"2026","author":[{"given":"Sergio Calero","family":"Martinez","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Jena University Hospital \u2013 Friedrich Schiller University Jena , Jena ,","place":["Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lydia","family":"Karamani","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Jena University Hospital \u2013 Friedrich Schiller University Jena , Jena ,","place":["Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Heike","family":"de Vries","sequence":"additional","affiliation":[{"name":"Department of Pediatric Neurology, University Hospital of Jena, Friedrich-Schiller-University Jena ,","place":["Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul-Christian","family":"Kr\u00fcger","sequence":"additional","affiliation":[{"name":"Department of Diagnostic and Interventional Radiology \u2013 Section of Pediatric Radiology, University Hospital of Jena, Friedrich-Schiller-University Jena ,","place":["Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christian","family":"Senft","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Jena University Hospital \u2013 Friedrich Schiller University Jena , Jena ,","place":["Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1825-3877","authenticated-orcid":false,"given":"Nazeer","family":"Aboud","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Jena University Hospital \u2013 Friedrich Schiller University Jena , Jena ,","place":["Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2026,10,19]]},"reference":[{"key":"2026110401420886600_ref1","doi-asserted-by":"publisher","first-page":"e8234","DOI":"10.1002\/ccr3.8234","article-title":"The endoscopic treatment of fourth ventricle outlet obstruction: report of two children and systematic review","volume":"11","author":"Mulhem","year":"2023","journal-title":"Clin Case Rep"},{"key":"2026110401420886600_ref2","doi-asserted-by":"publisher","first-page":"359","DOI":"10.1159\/000511088","article-title":"Fourth ventricle outlet obstruction and diverticular enlargement of Luschka foramina in a child with down syndrome","volume":"55","author":"Orlando","year":"2020","journal-title":"Pediatr Neurosurg"},{"key":"2026110401420886600_ref3","doi-asserted-by":"publisher","first-page":"170","DOI":"10.4103\/ajns.AJNS_67_20","article-title":"Endoscopic third ventriculostomy in the fourth ventricle outlet obstruction associated with Chiari malformation type I and syringomyelia: case report","volume":"16","author":"Salem-Memou","year":"2021","journal-title":"Asian J Neurosurg"},{"key":"2026110401420886600_ref4","doi-asserted-by":"publisher","first-page":"72","DOI":"10.2176\/nmccrj.2014-0245","article-title":"Fourth ventriculostomy in occlusion of the foramen of Magendie associated with Chiari malformation and syringomyelia","volume":"2","author":"Orakdogen","year":"2015","journal-title":"NMC Case Report Journal"},{"key":"2026110401420886600_ref5","doi-asserted-by":"publisher","DOI":"10.5772\/intechopen.75394","article-title":"Endoscopic third ventriculostomy","author":"Unal","year":"2018","journal-title":"InTech"},{"key":"2026110401420886600_ref6","doi-asserted-by":"publisher","DOI":"10.5772\/intechopen.72889","article-title":"Presentation of the success rate of ETV in distinct indication cases of hydrocephalus","author":"Oertel","year":"2018","journal-title":"InTech"},{"key":"2026110401420886600_ref7","doi-asserted-by":"publisher","first-page":"01","DOI":"10.31579\/2578-8868\/274","article-title":"Endoscopic third ventriculostomy for obstructive hydrocephalus in children;
