We report the case of a 7\u2010year\u2010old boy with a history of a VP shunt for post\u2010traumatic hydrocephalus who presented with progressive drowsiness and gait disturbances. While initial CT imaging suggested a tumor, subsequent MRI confirmed a markedly dilated fourth ventricle, diagnosing TFV. The patient underwent open posterior fenestration with microsurgical arachnoid adhesiolysis, which successfully restored cerebrospinal fluid dynamics. This intervention resulted in the complete resolution of his neurological symptoms at 1\u2010month follow\u2010up. This case highlights the importance of suspecting TFV in shunted patients with new neurological deficits and demonstrates that open fenestration is a highly effective treatment strategy, particularly when dense adhesions are clinically suspected. Timely diagnosis with advanced imaging and prompt surgical intervention are crucial to prevent irreversible damage and ensure favorable neurological outcomes.<\/jats:p>","DOI":"10.1002\/ccr3.72748","type":"journal-article","created":{"date-parts":[[2026,6,11]],"date-time":"2026-06-11T05:26:58Z","timestamp":1781155618000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Trapped Fourth Ventricle in a Pediatric Patient With a History of Post\u2010Traumatic Hydrocephalus and Ventriculoperitoneal Shunt: A Case Report and Literature Review"],"prefix":"10.1002","volume":"14","author":[{"given":"Muhammad","family":"Hamza","sequence":"first","affiliation":[{"name":"Saidu Medical College  Swat Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Muhammad","family":"Ibrahim","sequence":"additional","affiliation":[{"name":"Bannu Medical College  Bannu Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ihsan","family":"Ullah","sequence":"additional","affiliation":[{"name":"Khyber Medical University  Peshawar Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rehmat","family":"Farhaj","sequence":"additional","affiliation":[{"name":"Saidu Medical College  Swat Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fazeela","family":"Bibi","sequence":"additional","affiliation":[{"name":"Jinnah Medical and Dental College  Karachi Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-6138-6684","authenticated-orcid":false,"given":"Khalil","family":"El Abdi","sequence":"additional","affiliation":[{"name":"Faculty of Medicine and Pharmacy of Rabat Mohammed V University  Rabat Morocco"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bilal","family":"Aslam","sequence":"additional","affiliation":[{"name":"University of Lahore  Lahore Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vohra Maham","family":"Hassan","sequence":"additional","affiliation":[{"name":"Jinnah Medical and Dental College  Karachi Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-7885-6214","authenticated-orcid":false,"given":"Said Hamid","family":"Sadat","sequence":"additional","affiliation":[{"name":"Kabul University of Medical Sciences, Abu Ali Ibn Sina  Kabul Afghanistan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,6,10]]},"reference":[{"key":"e_1_2_14_2_1","volume-title":"Hydrocephalus","author":"Koleva M.","year":"2023"},{"key":"e_1_2_14_3_1","volume-title":"Hydrocephalus in Infants and Children: Diagnosis & Treatment","author":"Hydrocephalus Association","year":"2020"},{"key":"e_1_2_14_4_1","volume-title":"Physiology, Cerebral Spinal Fluid (CSF)","author":"Telano L.
