We report a unique case of intraventricular trigone PXA, a rare location that mimicked an intraventricular meningioma on imaging. A 26-year-old male presented with progressive visual loss, and magnetic resonance imaging revealed a well-defined lesion in the right lateral ventricle. The patient underwent subtotal tumor resection, followed by adjuvant radiotherapy. Histopathological analysis confirmed PXA with BRAF V600E mutation, and subsequent imaging showed successful tumor control with no recurrence after 2 years. This case highlights the importance of differentiating PXA from other neoplasms, such as meningiomas, and demonstrates the favorable prognosis of PXA when appropriately managed.<\/jats:p>","DOI":"10.1055\/s-0045-1809031","type":"journal-article","created":{"date-parts":[[2025,5,1]],"date-time":"2025-05-01T18:47:59Z","timestamp":1746125279000},"page":"646-650","source":"Crossref","is-referenced-by-count":0,"title":["Intraventricular Trigone Pleomorphic Xanthoastrocytoma: A Rare Presentation with Favorable Prognosis in a Young Adult\u2014A Case Report"],"prefix":"10.1055","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4809-4205","authenticated-orcid":false,"given":"Chonnawee","family":"Chaisawasthomrong","sequence":"additional","affiliation":[{"name":"Division of Neurosurgery, Department of Surgery, Ratchaburi Hospital, Ratchaburi, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2025,5,1]]},"reference":[{"issue":"09","key":"ref1","doi-asserted-by":"crossref","first-page":"2033","DOI":"10.1002\/(SICI)1097-0142(19990501)85:9<2033::AID-CNCR22>3.0.CO;2-Z","article-title":"Pleomorphic xanthoastrocytoma: what do we really know about it?","volume":"85","author":"C Giannini","year":"1999","journal-title":"Cancer"},{"issue":"06","key":"ref2","doi-asserted-by":"crossref","first-page":"803","DOI":"10.1007\/s00401-016-1545-1","article-title":"The 2016 World Health Organization classification of tumors of the central nervous system: a summary","volume":"131","author":"D N Louis","year":"2016","journal-title":"Acta Neuropathol"},{"issue":"07","key":"ref3","doi-asserted-by":"crossref","first-page":"670","DOI":"10.1038\/s41374-021-00708-0","article-title":"The evolution of pleomorphic xanthoastrocytoma: from genesis to molecular alterations and mimics","volume":"102","author":"S Mahajan","year":"2022","journal-title":"Lab Invest"},{"key":"ref4","doi-asserted-by":"crossref","first-page":"25","DOI":"10.1016\/j.wneu.2020.05.117","article-title":"Spinal pleomorphic xanthoastrocytoma: case report and literature review","volume":"141","author":"D Tan","year":"2020","journal-title":"World Neurosurg"},{"key":"ref5","doi-asserted-by":"crossref","first-page":"72","DOI":"10.25259\/SNI-83-2019","article-title":"Suprasellar pleomorphic xanthoastrocytoma: a case report","volume":"10","author":"E Telemi","year":"2019","journal-title":"Surg Neurol Int"},{"issue":"02","key":"ref6","doi-asserted-by":"crossref","first-page":"226","DOI":"10.31486\/toj.18.0156","article-title":"Pleomorphic xanthoastrocytoma of the pineal region in a pediatric patient with neurofibromatosis type 1","volume":"20","author":"J A Hanna","year":"2020","journal-title":"Ochsner J"},{"key":"ref7","doi-asserted-by":"crossref","first-page":"577","DOI":"10.1016\/j.wneu.2020.04.113","article-title":"Cerebellar pleomorphic xanthoastrocytoma with BRAF V600E mutation","volume":"139","author":"S H Kim","year":"2020","journal-title":"World Neurosurg"},{"issue":"01","key":"ref8","doi-asserted-by":"crossref","first-page":"30","DOI":"10.1007\/s002340050700","article-title":"Pleomorphic xanthoastrocytoma with CT and MRI appearance of meningioma","volume":"41","author":"A Pierallini","year":"1999","journal-title":"Neuroradiology"},{"issue":"01","key":"ref9","doi-asserted-by":"crossref","first-page":"63","DOI":"10.1023\/A:1010648006319","article-title":"Pleomorphic xanthoastrocytomas: immunohistochemistry, grading and clinico-pathologic correlations.
