Intraventricular meningiomas are rare intraventricular tumors presenting with symptoms of hydrocephalus, headache, and neurological deficits. The rarity of choroid plexus papillomas is highlighted in medical diagnostics, with the majority of these findings being incidental within the setting of obstructive hydrocephalus. We present the case of a 66-year-old male patient who exhibited symptoms of headaches. Magnetic resonance imaging showed the presence of an intraventricular tumor in the region of the trigone of the right lateral ventricle, which was assessed for surgical removal. A postoperative hemorrhage necessitated a reoperation, after which the patient began to gradually recover. Hemianopsian disturbances persisted during and after his hospital stay. This report describes a rare case of concurrent choroid plexus papilloma and ventricular meningioma, manifesting as a single tumor mass.<\/jats:p>","DOI":"10.3390\/medicina60122100","type":"journal-article","created":{"date-parts":[[2024,12,23]],"date-time":"2024-12-23T05:58:27Z","timestamp":1734933507000},"page":"2100","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["A Rare Case of Concurrent Intraventricular Meningioma and Choroid Plexus Papilloma: A Case Report"],"prefix":"10.3390","volume":"60","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4015-3514","authenticated-orcid":false,"given":"Daniel","family":"Markov","sequence":"first","affiliation":[{"name":"Department of General and Clinical Pathology, Medical University of Plovdiv, 4002 Plovdiv, Bulgaria"},{"name":"Department of Clinical Pathology, University Multidisciplinary Hospital for Active Treatment (UMHAT) \u201cPulmed\u201d, 4002 Plovdiv, Bulgaria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-1460-3522","authenticated-orcid":false,"given":"Kristian","family":"Bechev","sequence":"additional","affiliation":[{"name":"Department of General and Clinical Pathology, Medical University of Plovdiv, 4002 Plovdiv, Bulgaria"},{"name":"Neurological Surgery, Pulmed Univeristy Hospital, 4000 Plovdiv, Bulgaria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-9425-2539","authenticated-orcid":false,"given":"Usman","family":"Khalid","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Medical University of Plovdiv, 4002 Plovdiv, Bulgaria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vladimir","family":"Aleksiev","sequence":"additional","affiliation":[{"name":"Department of Thoracic Surgery, UMHAT \u201cKaspela\u201d, 4002 Plovdiv, Bulgaria"},{"name":"Department of Cardiovascular Surgery, Medical University of Plovdiv, 4002 Plovdiv, Bulgaria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-9169-5945","authenticated-orcid":false,"given":"Galabin","family":"Markov","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Medical University of Plovdiv, 4002 Plovdiv, Bulgaria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elena","family":"Poryazova","sequence":"additional","affiliation":[{"name":"Department of General and Clinical Pathology, Medical University of Plovdiv, 4002 Plovdiv, Bulgaria"},{"name":"Department of Clinical Pathology, University Multidisciplinary Hospital for Active Treatment (UMHAT) \u201cPulmed\u201d, 4002 Plovdiv, Bulgaria"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,12,22]]},"reference":[{"key":"ref_1","unstructured":"Mayol Del Valle, M., and De Jesus, O.
