The authors have reviewed the clinical features and treatment responses of eight children with these rare tumors, the largest series to date.<\/jats:p>\n<jats:p content-type=\"fine-print\">In this series, the medulloepitheliomas were equally distributed between supratentorial and infratentorial primary sites. Four patients underwent gross- or near-total resections, one patient's tumor was partially resected, and one patient had biopsy only. Biopsy and ablative surgery were not attempted in two children with pontine tumors. Treatment included both radiation and chemotherapy (four patients), radiation alone (one patient), chemotherapy alone (one patient), and no postoperative treatment (two patients). Six patients died with a mean survival of 10 months and two are disease free with neurological impairment. Both long-term survivors underwent gross-total resections of their tumors. Postmortem examination revealed diffuse CNS tumor dissemination in four patients.<\/jats:p>\n<jats:p content-type=\"fine-print\">Medulloepithelioma, often confused with less aggressive PNETs, can mimic intrinsic brainstem glioma, responds poorly to treatment, and is prone to CNS dissemination at the time of tumor progression.<\/jats:p>","DOI":"10.3171\/jns.1996.84.3.0430","type":"journal-article","created":{"date-parts":[[2009,6,8]],"date-time":"2009-06-08T23:42:43Z","timestamp":1244504563000},"page":"430-436","source":"Crossref","is-referenced-by-count":73,"title":["Central nervous system medulloepithelioma: a series of eight cases including two arising in the pons"],"prefix":"10.3171","volume":"84","author":[{"given":"Patricia T.","family":"Molloy","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anthony T.","family":"Yachnis","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lucy B.","family":"Rorke","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"James J.","family":"Dattilo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael N.","family":"Needle","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"William S.","family":"Millar","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joel W.","family":"Goldwein","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Leslie N.","family":"Sutton","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peter C.","family":"Phillips","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","doi-asserted-by":"crossref","first-page":"256","DOI":"10.1097\/00005072-198305000-00004","volume":"42","author":"Auer RN","year":"1983","journal-title":"J Neuropathol Exp Neurol"},{"key":"b2","unstructured":"Bailey P, Cushing H:A Classification of Tumors of the Glioma Group on a Histogenetic Basis with a Correlated Study of Progress.Philadelphia: JB Lippincott, 1926, pp 54\u201356"},{"key":"b3","unstructured":"Barkovich AJ, Edwards MSB:Pediatric Neuroimaging.
