Falcotentorial location is rare. There is almost no evidence regarding resection using a 3D-4K exoscope.<\/jats:p>\n <\/jats:sec>\n \n Methods:<\/jats:title>\n We present the case of a 59-year-old female patient with a tumor adjacent to the falx and tentorium, with extension to the pineal region. Falcotentorial meningioma was considered the first diagnostic possibility. A parieto-occipital interhemispheric transtentorial approach was chosen, guided by neuronavigation and using a 3D-4K robotic arm exoscope (3DRAE); gross total resection was achieved. Postoperatively, the patient presented no complications, and magnetic resonance imaging confirmed complete resection. However, the pathology report indicated a grade 3 SFT.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n This case highlights the importance of an appropriate approach based on the morphology and anatomical location of the tumor lesion in the CNS. It also highlights the usefulness of neuronavigation and the 3DRAE in tumors located in areas that are highly complex to approach. On the other hand, it is important to remember the difficulty in differentiating a meningioma from an SFT preoperatively, which could lead to complications during surgery. Finally, to the best of our knowledge, this is the first reported case of a falcotentorial SFT intervened via a parieto-occipital interhemispheric transtentorial approach using 3DRAE.<\/jats:p>\n <\/jats:sec>\n \n Conclusion:<\/jats:title>\n Neuronavigation and the 3DRAE were useful for adequate tumor localization, with complete resection and fewer complications. We believe that, in this specific approach, the exoscope proved extremely useful.<\/jats:p>\n <\/jats:sec>","DOI":"10.25259\/sni_734_2026","type":"journal-article","created":{"date-parts":[[2026,8,28]],"date-time":"2026-08-28T13:12:43Z","timestamp":1787922763000},"page":"482","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Parieto-occipital interhemispheric transtentorial resection of a falcotentorial solitary fibrous tumor using a 3D-4K exoscope: Technical nuances and illustrative case"],"prefix":"10.25259","volume":"17","author":[{"given":"Eduardo","family":"Ichikawa-Escamilla","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, National Medical Center, XXI Century, Specialties Hospital, Instituto Mexicano del Seguro Social, Mexico City, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jes\u00fas Eduardo","family":"Falc\u00f3n-Molina","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, National Medical Center, XXI Century, Specialties Hospital, Instituto Mexicano del Seguro Social, Mexico City, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julio C\u00e9sar","family":"L\u00f3pez-Vald\u00e9s","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, National Medical Center, XXI Century, Specialties Hospital, Instituto Mexicano del Seguro Social, Mexico City, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Flavio","family":"Hern\u00e1ndez-Gonz\u00e1lez","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, National Medical Center, XXI Century, Specialties Hospital, Instituto Mexicano del Seguro Social, Mexico City, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carlos J.","family":"M\u00e1vita-Corral","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, National Medical Center, XXI Century, Specialties Hospital, Instituto Mexicano del Seguro Social, Mexico City, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marco A.","family":"Rodr\u00edguez-Florido","sequence":"additional","affiliation":[{"name":"Department of Neuropathology, National Medical Center, XXI Century, Specialties Hospital, Instituto Mexicano del Seguro Social, Mexico City, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pedro Adri\u00e1n","family":"Gonz\u00e1lez-Zavala","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, National Medical Center, XXI Century, Specialties Hospital, Instituto Mexicano del Seguro Social, Mexico City, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"10894","published-online":{"date-parts":[[2026,8,28]]},"reference":[{"key":"10.25259\/SNI_734_2026\/ref-1","doi-asserted-by":"crossref","first-page":"1637","DOI":"10.1016\/j.radcr.2021.04.008","article-title":"Intracranial solitary fibrous tumor\/hemangiopericytoma mimicking cystic meningioma: A case report and literature review","volume":"16","author":"Chikasue","year":"2021","journal-title":"Radiol Case Rep"},{"key":"10.25259\/SNI_734_2026\/ref-2","doi-asserted-by":"crossref","first-page":"11","DOI":"10.5334\/jbr-btr.1213","article-title":"Intracranial solitary fibrous tumor","volume":"101","author":"Claus","year":"2017","journal-title":"J Belg Soc Radiol"},{"key":"10.25259\/SNI_734_2026\/ref-4","doi-asserted-by":"crossref","first-page":"1299","DOI":"10.1007\/s10143-020-01335-x","article-title":"A review of solitary fibrous tumor\/hemangiopericytoma tumor and a comparison of risk factors for recurrence, metastases, and death among patients with spinal and intracranial tumors","volume":"44","author":"Giordan","year":"2021","journal-title":"Neurosurg Rev"},{"key":"10.25259\/SNI_734_2026\/ref-5","doi-asserted-by":"crossref","first-page":"e345","DOI":"10.1016\/j.wneu.2021.02.026","article-title":"Intracranial solitary fibrous tumor of the skull base: 2 Cases and systematic review of the literature","volume":"149","author":"Gopakumar","year":"2021","journal-title":"World Neurosurg"},{"key":"10.25259\/SNI_734_2026\/ref-6","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1002\/ajim.4700220103","article-title":"Primary neoplasms of the pleura.
