Diagnosis is challenging because it can mimic a variety of other lesions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CLINICAL PRESENTATION:<\/jats:title>\n                    <jats:p>A 71-year-old man presented after a fall because of imbalance. MRI of the head showed a homogenously enhancing 2-cm mass in the posterior aspect of the right lateral ventricle, with blood layering in the right occipital horn and adjacent parietal edema and leptomeningeal enhancement, as well as a pituitary lesion.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>DISCUSSION:<\/jats:title>\n                    <jats:p>The patient underwent a right parietal craniotomy for resection of the mass. The ventricle was accessed through a transsulcal approach through the intraparietal sulcus using a tubular retractor system. The mass was arising from the choroid plexus and dissected free in a piecemeal fashion. Postoperative imaging confirmed gross total resection, and the patient had an uneventful recovery.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSION:<\/jats:title>\n                    <jats:p>Here, we present the first case of a choroid plexus IVCM removed using a tubular retractor system. We demonstrate that this is a safe and effective approach for this rare lesion given the minimal traction on brain parenchyma and enhanced visualization of a deep-seated cavernoma in the lateral ventricle.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1227\/ons.0000000000000075","type":"journal-article","created":{"date-parts":[[2022,1,14]],"date-time":"2022-01-14T15:08:09Z","timestamp":1642172889000},"page":"e134-e137","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":9,"title":["Intraventricular Choroid Plexus Cavernoma Resection Using Tubular Retractor System and Exoscope Visualization: A Technical Case Report"],"prefix":"10.1227","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9516-7054","authenticated-orcid":false,"given":"Boyi","family":"Li","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, New York Medical College, Valhalla, New York, USA;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael G.","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Westchester Medical Center, New York Medical College, Valhalla, New York, USA;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jose","family":"Dominguez","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Westchester Medical Center, New York Medical College, Valhalla, New York, USA;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eric","family":"Feldstein","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, New York Medical College, Valhalla, New York, USA;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"George","family":"Kleinman","sequence":"additional","affiliation":[{"name":"Department of Pathology, Westchester Medical Center, New York Medical College, Valhalla, New York, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Simon","family":"Hanft","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Westchester Medical Center, New York Medical College, Valhalla, New York, USA;"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2022,1,14]]},"reference":[{"issue":"3","key":"R1-20251027","doi-asserted-by":"crossref","first-page":"233","DOI":"10.1055\/s-0034-1389093","article-title":"Therapeutic management of intraventricular cavernoma: case series and review of the literature","volume":"76","author":"Faropoulos","year":"2015","journal-title":"J Neurol Surg Part Cent Eur Neurosurg."},{"issue":"1","key":"R2-20251027","doi-asserted-by":"crossref","first-page":"140","DOI":"10.3171\/2009.3.JNS081693","article-title":"Intraventricular cerebral cavernomas: a series of 12 patients and review of the literature: clinical article","volume":"112","author":"Kivelev","year":"2010","journal-title":"J Neurosurg."},{"issue":"4","key":"R3-20251027","doi-asserted-by":"crossref","first-page":"518","DOI":"10.3171\/jns.1988.68.4.0518","article-title":"Clinical, radiological, and pathological spectrum of angiographically occult intracranial vascular malformations: analysis of 21 cases and review of the literature","volume":"68","author":"Lobato","year":"1988","journal-title":"J Neurosurg."},{"issue":"6","key":"R4-20251027","doi-asserted-by":"crossref","first-page":"1611","DOI":"10.3171\/2013.8.JNS1337","article-title":"Low-dose intravenous heparin infusion in patients with aneurysmal subarachnoid hemorrhage: a preliminary assessment","volume":"119","author":"Simard","year":"2013","journal-title":"J Neurosurg."},{"issue":"2","key":"R5-20251027","first-page":"59","article-title":"Cerebral cavernous haemangiomas or cavernomas.
