Clinical presentation was that of a rapidly growing tender exostosis, associated with headaches. History indicated that the tumor may have been present for more than 1 year. Skull x-rays showed marked diastasis of the coronal suture and a \u201cmottled\u201d appearance on the right frontal bone suggestive of a sarcoma. Bone scan further confirmed the presence of a malignant bone tumor. Computerized tomography scan showed the intracranial extension of the tumor and a follow-up scan allowed us to see the response of the tumor to therapy. Only two other cases with details as to intracranial localization were found in the literature.<\/jats:p>","DOI":"10.3171\/jns.1979.50.6.0811","type":"journal-article","created":{"date-parts":[[2009,5,7]],"date-time":"2009-05-07T15:35:46Z","timestamp":1241710546000},"page":"811-813","source":"Crossref","is-referenced-by-count":47,"title":["Localized primary intracranial Ewing's sarcoma of the orbital roof"],"prefix":"10.3171","volume":"50","author":[{"given":"Antonio","family":"Alvarez-Berdecia","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luis","family":"Schut","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Derek A.","family":"Bruce","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","series-title":"J Bone Joint Surg","first-page":"541","article-title":"Ewing's sarcoma.
