Most of the tumors were confined to a single compartment (infratentorial in 49.7%, supratentorial in 46.6%), while 3.8% of the tumors involved multiple compartments. The most common intracranial tumors were astrocytomas (35%), medulloblastomas (18.8%), craniopharyngiomas (11.3%) and ependymomas (10%). Pilocytic astrocytomas constituted 55% of all astrocytomas and 19.3% of all brain tumors, only slightly ahead of medulloblastomas. Less common types were primitive neuroectodermal tumors (2.7%), followed by meningiomas, germ cell tumors and choroid plexus tumors (2.4% each). According to the International Classification of Diseases for Oncology Coding (ICD-O-4), benign, borderline and malignant tumors constituted 7.54, 36.14 and 56.32%, respectively. &lt;b&gt;&lt;i&gt;Conclusion:&lt;\/i&gt;&lt;\/b&gt; The characteristics of pediatric intracranial tumors in Egypt are generally similar to those reported in the literature, with only minor differences.<\/jats:p>","DOI":"10.1159\/000337872","type":"journal-article","created":{"date-parts":[[2012,7,9]],"date-time":"2012-07-09T09:34:11Z","timestamp":1341826451000},"page":"385-395","source":"Crossref","is-referenced-by-count":32,"title":["Descriptive Epidemiology of Pediatric Intracranial Neoplasms in Egypt"],"prefix":"10.1159","volume":"47","author":[{"given":"Mohamed Ali","family":"El-Gaidi","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2012,7,7]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.ejca.2006.05.009"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1007%2Fs003810100496"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1007%2Fs003810050467"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1215%2F15228517-4-2-134"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1215%2FS115285170400050X"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1159%2F000321540"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1111%2Fj.1651-2227.2009.01417.x"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1093%2Fije%2Fdyg051"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1002%2F1097-0142%2820011215%2992%3A12%3C3155%3A%3AAID-CNCR10158%3E3.0.CO%3B2-C"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1007%2Fs003810050231"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1159%2F000090458"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1007%2Fs00381-008-0771-9"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.2176%2Fnmc.43.1"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1159%2F000113110"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1002%2Fcncr.21430"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1007%2Fs00381-001-0547-y"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1159%2F000327143"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1159%2F000086557"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1016%2F0090-3019%2893%2990029-Z"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.1007%2Fs00381-006-0198-0"},{"key":"ref21","doi-asserted-by":"publisher","DOI":"10.1007%2Fs00381-010-1097-y"},{"key":"ref22","doi-asserted-by":"publisher","DOI":"10.1159%2F000149905"},{"key":"ref23","doi-asserted-by":"publisher","DOI":"10.1007%2FBF00163535"},{"key":"ref24","doi-asserted-by":"publisher","DOI":"10.1016%2FS1470-2045%2807%2970207-3"},{"key":"ref25","doi-asserted-by":"publisher","DOI":"10.1016%2FS0090-3019%2896%2900487-9"},{"key":"ref26","doi-asserted-by":"publisher","DOI":"10.1007%2FBF00306267"},{"key":"ref27","doi-asserted-by":"publisher","DOI":"10.1159%2F000210053"},{"key":"ref28","doi-asserted-by":"publisher","DOI":"10.1016%2FS1470-2045%2804%2901650-X"}],"container-title":["Pediatric Neurosurgery"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/337872","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/337872","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T18:14:49Z","timestamp":1745432089000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000337872"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2011]]},"references-count":28,"journal-issue":{"issue":"6","published-online":{"date-parts":[[2012,7,1]]},"published-print":{"date-parts":[[2012,7,25]]}},"URL":"https:\/\/doi.org\/10.1159\/000337872","archive":["Portico"],"relation":{},"ISSN":["1016-2291","1423-0305"],"issn-type":[{"value":"1016-2291","type":"print"},{"value":"1423-0305","type":"electronic"}],"subject":[],"published":{"date-parts":[[2011]]}}}
