Diagnostic cerebral angiography demonstrated predominant supply from the left anterior choroidal artery. The lesion underwent endovascular embolization with Onyx-18, achieving complete angiographic devascularization without procedural complication. Planned resection was initially deferred because of intercurrent rhinovirus\/enterovirus infection in the acute postprocedural period and the favorable embolization result. Serial follow-up imaging demonstrated a progressive decrease in lesion size and enhancement, followed by radiographic stability of a small treated residual lesion without evidence of dissemination or new complication. The patient remained neurologically stable throughout follow-up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>LESSONS<\/jats:title>\n                    <jats:p>Although resection remains the standard treatment for CPP, stand-alone embolization may represent a feasible strategy in highly selected circumstances, provided that close long-term surveillance is maintained.<\/jats:p>\n                    <jats:p>\n                      <jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" ext-link-type=\"uri\" xlink:href=\"https:\/\/thejns.org\/doi\/10.3171\/CASE26348\">https:\/\/thejns.org\/doi\/10.3171\/CASE26348<\/jats:ext-link>\n                    <\/jats:p>\n                  <\/jats:sec>","DOI":"10.3171\/case26348","type":"journal-article","created":{"date-parts":[[2026,7,1]],"date-time":"2026-07-01T00:19:00Z","timestamp":1782865140000},"source":"Crossref","is-referenced-by-count":0,"title":["Embolization of a pediatric choroid plexus papilloma as a stand-alone treatment strategy: illustrative case"],"prefix":"10.3171","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0298-1052","authenticated-orcid":true,"given":"Lucas P.","family":"Mitre","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, UT Southwestern Medical Center, Dallas, Texas"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4818-019X","authenticated-orcid":true,"given":"Ishav Y.","family":"Shukla","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, UT Southwestern Medical Center, Dallas, Texas"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bradley","family":"Weprin","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, UT Southwestern Medical Center, Dallas, Texas"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9165-2714","authenticated-orcid":true,"given":"Rafael","family":"De Oliveira Sillero","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, UT Southwestern Medical Center, Dallas, Texas"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"issue":"2","key":"bib1","series-title":"Childs Nerv Syst","first-page":"429","article-title":"Pre-operative embolization for staged treatment of infantile choroid plexus papilloma","volume":"38","author":"Mangham","year":"2022","unstructured":"Mangham WMElijovich LLee-Diaz JAOrr BAGienapp AJBoop FA.Pre-operative embolization for staged treatment of infantile choroid plexus papilloma.
