In this report, the authors present the case of an 8-year-old boy with a history of generalized tonic\u2013clonic seizures who was found to harbor a meningeal osteosarcoma within the sylvian fissure. Initial working diagnoses included meningioma and glioma. After tumor enlargement and progressive symptoms, the patient underwent a large frontotemporal craniotomy and complete resection of the lesion, which recurred 6 and 12 months after the initial surgery and was surgically treated after each recurrence. The rarity of primary meningeal osteosarcomas can make their diagnosis difficult, and histopathological evaluation is mandatory for diagnosis. Because of their fast progression, they must be treated aggressively by means of surgery, chemotherapy, and radiotherapy.<\/jats:p>","DOI":"10.3171\/ped\/2008\/1\/4\/325","type":"journal-article","created":{"date-parts":[[2008,3,31]],"date-time":"2008-03-31T18:11:23Z","timestamp":1206987083000},"page":"325-329","source":"Crossref","is-referenced-by-count":10,"title":["Primary meningeal osteosarcoma of the brain during childhood"],"prefix":"10.3171","volume":"1","author":[{"given":"Adnan","family":"Dagcinar","sequence":"first","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fatih","family":"Bayrakli","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ozlem","family":"Yapicier","sequence":"additional","affiliation":[{"name":"Pathology, Marmara University School of Medicine, Istanbul, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Memet","family":"Ozek","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1-0010325","series-title":"Eur J Radiol","doi-asserted-by":"publisher","first-page":"193","DOI":"10.1016\/0720-048X(92)90104-H","article-title":"Primary osteogenic sarcoma of the falx cerebri: a case report","volume":"15","author":"Ali Zirh","year":"1992"},{"key":"b2-0010325","series-title":"Neurosurgery","doi-asserted-by":"publisher","first-page":"447","DOI":"10.1097\/00006123-200008000-00036","article-title":"Osteosarcoma of the temporal fossa with hemorrhagic presentation: case report","volume":"47","author":"Alleyne","year":"2000"},{"key":"b3-0010325","series-title":"J Pathol","doi-asserted-by":"publisher","first-page":"253","DOI":"10.1002\/path.1711160408","article-title":"Mixed mesenchymal differentiation in meningiomas","volume":"116","author":"Ball","year":"1975"},{"key":"b4-0010325","series-title":"Am J Clin Oncol","doi-asserted-by":"publisher","first-page":"418","DOI":"10.1097\/00000421-200108000-00025","article-title":"Primary osteogenic sarcoma arising from the dura mater: case report","volume":"24","author":"Bar-Sela","year":"2001"},{"key":"b5-0010325","series-title":"J Neurooncol","doi-asserted-by":"publisher","first-page":"209","DOI":"10.1023\/A:1005756930169","article-title":"Primary intracerebral osteosarcoma: a case report","volume":"32","author":"Bauman","year":"1997"},{"key":"b6-0010325","series-title":"Surg Neurol","doi-asserted-by":"publisher","first-page":"234","DOI":"10.1016\/S0090-3019(02)00864-9","article-title":"Primary osteogenic sarcoma of the skull","volume":"58","author":"Bose","year":"2002"},{"key":"b7-0010325","series-title":"Cancer","doi-asserted-by":"publisher","first-page":"8","DOI":"10.1002\/(SICI)1097-0142(19980101)82:1<8::AID-CNCR3>3.0.CO;2-W","article-title":"Sarcoma arising in irradiated bone: report of eleven cases. 1948","volume":"82","author":"Cahan","year":"1998"},{"key":"b8-0010325","series-title":"Arch Pathol Lab Med","first-page":"737","article-title":"Primary intracerebellar osteosarcoma arising within an epidermoid cyst","volume":"122","author":"Cannon","year":"1998"},{"key":"b9-0010325","series-title":"J Neurosurg Sci","first-page":"177","article-title":"Primary osteosarcoma of the skull.
