Imaging identified a left atrial intraventricular mass and a vague adjacent second periventricular cystic lesion. A guided trans-sulcal approach via a left parietal craniotomy resulted in a gross total resection of both lesions. These represented two distinct lesions, the periventricular cystic lesion was an extraventricular neurocytoma (EVN) and a World Health Organization grade 1 choroid plexus papilloma (CPP). The neurocytoma required methylation studies for confirmatory diagnosis. The patient had an uneventful recovery with a normal neurological exam at 12-weeks. This documents the occurrence of two distinct central nervous system tumors, a CPP and an EVN presenting with an intraventricular hemorrhage.<\/jats:p>","DOI":"10.1093\/jscr\/rjad699","type":"journal-article","created":{"date-parts":[[2024,1,11]],"date-time":"2024-01-11T22:16:49Z","timestamp":1705011409000},"source":"Crossref","is-referenced-by-count":2,"title":["Clinical rarity: simultaneous choroid plexus papilloma and extraventricular neurocytoma presenting as intraventricular hemorrhage in an adolescent"],"prefix":"10.1093","volume":"2024","author":[{"given":"Kaleb","family":"Derouen","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Children\u2019s Hospital of New Orleans , New Orleans, LA , United States"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kierany","family":"Shelvin","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Children\u2019s Hospital of New Orleans , New Orleans, LA , United States"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wesley","family":"Shoap","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Children\u2019s Hospital of New Orleans , New Orleans, LA , United States"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Randall","family":"Craver","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Children\u2019s Hospital of New Orleans , New Orleans, LA , United States"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jerome","family":"Volk","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Children\u2019s Hospital of New Orleans , New Orleans, LA , United States"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oritsejolomi A","family":"Roberts","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Children\u2019s Hospital of New Orleans , New Orleans, LA , United States"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2024,1,11]]},"reference":[{"key":"2024011122163236000_ref1","doi-asserted-by":"crossref","first-page":"745","DOI":"10.1007\/s00701-019-03832-5","article-title":"Management of choroid plexus tumors\u2014an institutional experience","volume":"161","author":"Hosmann","year":"2019","journal-title":"Acta Neurochir"},{"key":"2024011122163236000_ref2","doi-asserted-by":"crossref","first-page":"1086","DOI":"10.1038\/sj.bjc.6600609","article-title":"Choroid plexus tumours","volume":"87","author":"Wolff","year":"2002","journal-title":"Br J Cancer"},{"key":"2024011122163236000_ref3","doi-asserted-by":"crossref","first-page":"427","DOI":"10.1007\/s11060-017-2384-1","article-title":"Choroid plexus tumors in adult and pediatric populations: the Cleveland Clinic and university hospitals experience","volume":"132","author":"Bahar","year":"2017","journal-title":"J Neuro-Oncol"},{"key":"2024011122163236000_ref4","doi-asserted-by":"crossref","first-page":"905","DOI":"10.1002\/pbc.23349","article-title":"Choroid plexus tumors;
