A 15-year-old girl presented with scintillation, diplopia, and papilledema. Computed tomography and MRI studies revealed a huge irregularly shaped tumor located in the right occipital and suboccipital regions. The tumor, which had both intra- and extradural components, showed marked enhancement and invasion of the overlying occipital bone. Angiography revealed marked tumor stain, with blood supply mainly from a large branch of the left posterior meningeal artery. Therefore, this lesion was diagnosed as a tentorium-based extraaxial tumor. For differential diagnosis, meningioma, hemangiopericytoma, and malignant skull tumor were considered. Tumor feeders were endovascularly embolized with particles of polyvinyl alcohol. On the following day, the tumor was safely gross totally removed with minimum blood loss. Histopathological examination confirmed the diagnosis of cavernous angioma. To date, there have been no reports of tentorium-based cavernous angiomas endovascularly embolized preoperatively. A tentorial cavernous angioma is most likely to show massive intraoperative bleeding. Therefore, preoperative embolization appears to be quite useful for safe maximum resection. Hence, the authors assert that the differential diagnosis of tentorium-based tumors should include tentorial cavernous angioma, for which preoperative endovascular embolization should be considered.<\/jats:p>","DOI":"10.3171\/2014.4.peds13628","type":"journal-article","created":{"date-parts":[[2014,5,9]],"date-time":"2014-05-09T13:58:09Z","timestamp":1399643889000},"page":"43-47","source":"Crossref","is-referenced-by-count":11,"title":["Successful removal of a huge hypervascular tentorial cavernous angioma after preoperative endovascular embolization"],"prefix":"10.3171","volume":"14","author":[{"given":"Junichi","family":"Yoshimura","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshihiro","family":"Tsukamoto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masakazu","family":"Sano","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hitoshi","family":"Hasegawa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazuhiko","family":"Nishino","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akihiko","family":"Saito","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masafumi","family":"Fukuda","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kouichirou","family":"Okamoto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yukihiko","family":"Fujii","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1-peds13628","series-title":"Clin Neurol Neurosurg","doi-asserted-by":"publisher","first-page":"937","DOI":"10.1016\/j.clineuro.2011.07.007","article-title":"Giant tentorial cavernous hemangioma: case report and review of literature","volume":"113","author":"Bhatia","year":"2011"},{"key":"b2-peds13628","series-title":"Folia Hered Pathol (Milano)","first-page":"163","article-title":"Report of a case of cavernous hemangioma of the dura mater in a 2-day old newborn","volume":"12","author":"Canevini","year":"1963"},{"key":"b3-peds13628","series-title":"Acta Neurochir (Wien)","doi-asserted-by":"publisher","first-page":"1091","DOI":"10.1007\/s00701-005-0567-6","article-title":"Unusual locations for cavernous hemangiomas: report of two cases and review of the literature","volume":"147","author":"D\u00f6rner","year":"2005"},{"key":"b4-peds13628","series-title":"Riv Patol Nerv Ment","first-page":"214","article-title":"Considerazioni su un caso di angioma della falce","volume":"68","author":"Fracasso","year":"1947"},{"key":"b5-peds13628","series-title":"J Postgrad Med","first-page":"222","article-title":"Dural cavernous haemangioma of posterior cranial fossa","volume":"39","author":"Goel","year":"1993"},{"key":"b6-peds13628","series-title":"Pediatr Neurosurg","doi-asserted-by":"publisher","first-page":"105","DOI":"10.1159\/000121105","article-title":"Dural cavernous angiomas in a child","volume":"25","author":"Hsiang","year":"1996"},{"key":"b7-peds13628","series-title":"Fortschr Geb Rontgenstr Nuklearmed","first-page":"325","article-title":"[Vascular malformations and vascular tumors of the external carotid artery and dura.]","volume":"109","author":"Huber","year":"1968"},{"key":"b8-peds13628","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"503","DOI":"10.3171\/jns.2000.92.3.0503","article-title":"Giant interdural cavernous hemangioma at the convexity.
