Dorfman, is a rare benign histiocytic proliferative disorder, classically presenting with massive lymphadenopathy and a self-limiting clinical course.\n                    <jats:sup>1<\/jats:sup>\n                    Isolated intracranial skull base involvement is extremely rare and often resembles meningiomas, schwannomas, or other benign skull base lesions.\n                    <jats:sup>2<\/jats:sup>\n                    The disease is difficult to diagnose radiographically, and tissue diagnosis with open skull base approaches has significant perioperative risks.\n                    <jats:sup>2,3<\/jats:sup>\n                    We present the case of a 48-yr-old Caucasian male presenting with progressively worsening headaches, giddiness, hearing difficulty, and diplopia. Magnetic resonance imaging of the brain revealed T1-weighted isointense, T2-weighted hypointense, and contrast-enhancing dural-based lesion in the left cerebellopontine angle. The patient underwent maximally safe resection of the lesion through the retromastoid approach with careful preservation of the lower cranial nerve complex. The intraoperative findings of a variegated and lobulated mass adherent to the skull base, the surgical strategy of safe resection, and eventual good outcome in this patient are depicted in this 3-dimensional video presentation. The majority of patients with skull base Rosai\u2013Dorfman disease reported in literature have had stable or regression of disease (78%) after initial conservative surgical treatment and hence aggressive surgical resection is of unproven efficacy.\n                    <jats:sup>3<\/jats:sup>\n                  <\/jats:p>\n                  <jats:p>\u2003The patient has consented to depiction of his surgical video and intraoperative images in this video manuscript.<\/jats:p>","DOI":"10.1093\/ons\/opy121","type":"journal-article","created":{"date-parts":[[2018,5,21]],"date-time":"2018-05-21T05:46:03Z","timestamp":1526881563000},"page":"E10-E11","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Retromastoid Approach for Posterior Fossa Skull Base Rosai\u2013Dorfman Disease\u2014A Rare Pathology: 3-Dimensional Operative Video"],"prefix":"10.1227","volume":"16","author":[{"given":"Anil","family":"Nanda","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Louisiana State University Health Sciences Centre, Shreveport, Louisiana"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amey R","family":"Savardekar","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Louisiana State University Health Sciences Centre, Shreveport, Louisiana"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Devi Prasad","family":"Patra","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Louisiana State University Health Sciences Centre, Shreveport, Louisiana"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rimal Hanif","family":"Dossani","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Louisiana State University Health Sciences Centre, Shreveport, Louisiana"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria-Magdalena","family":"Georgescu","sequence":"additional","affiliation":[{"name":"Department of Pathology and Translational Pathobiology, Louisiana State University Health Sciences Centre, Shreveport, Louisiana"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2019,1]]},"reference":[{"issue":"1","key":"bib1-20240909","first-page":"661.e5","article-title":"Sinus histiocytosis with massive lymphadenopathy.
