They are often slow-growing and may present with nonspecific radiological features, complicating diagnosis.<\/jats:p>\n                  <jats:p>We report the case of a 48-year-old female with progressive left frontotemporal bulging over 12 months, without neurological deficits. Imaging revealed an osteoblastic lesion in the left sphenoid and temporal bones, causing mild compression of adjacent structures. The patient underwent craniectomy with complete tumor resection and immediate cranioplasty using a preplanned customized prosthesis. Histopathology and immunohistochemistry confirmed a meningothelial meningioma, with tumor cells confined to intertrabecular bone spaces and free surgical margins, consistent with a primary intraosseous origin. Postoperative follow-up demonstrated excellent cosmetic results and no recurrence.<\/jats:p>\n                  <jats:p>PIMs pose diagnostic and therapeutic challenges due to their rarity and nonspecific imaging features. Histopathology remains essential for definitive diagnosis. Preoperative 3D prototyping and customized prosthesis planning can optimize surgical reconstruction, reduce deformities, and improve cosmetic and functional outcomes. This case highlights the importance of integrating clinicoradiological evaluation, histopathology, and modern reconstructive techniques to achieve complete resection and minimize recurrence.<\/jats:p>","DOI":"10.1055\/a-2813-1643","type":"journal-article","created":{"date-parts":[[2026,2,19]],"date-time":"2026-02-19T00:01:06Z","timestamp":1771459266000},"page":"e62-e68","source":"Crossref","is-referenced-by-count":0,"title":["Primary Intraosseous Meningioma of the Sphenoid-Temporal Bone with Single-Stage, 3D-Planned Cranioplasty: Case Report"],"prefix":"10.1055","volume":"87","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9419-7777","authenticated-orcid":false,"given":"Arthur F. de","family":"Mattos","sequence":"additional","affiliation":[{"name":"Medical Department, Anhembi Morumbi School of Medicine, S\u00e3o Paulo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mariana S.","family":"Shima","sequence":"additional","affiliation":[{"name":"Medical Department, Universidade Municipal de S\u00e3o Caetano do Sul, S\u00e3o Paulo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lucas P.","family":"Chaves","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Hospital Militar de \u00c1rea de S\u00e3o Paulo, S\u00e3o Paulo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jo\u00e3o V.
