It may also be acquired after repeated lumbar punctures or lumboperitoneostomy. The occurrence of cerebellar herniation after derivation of intracranial arachnoid cyst is extremely rare, and there are only three cases reported in the medical literature. We present the case of a 9-year-old boy with precocious puberty and suprasellar arachnoid cyst who developed a symptomatic herniation of the cerebellar tonsils three years after a cystoperitoneostomy. The patient underwent a suboccipital craniectomy with duraplasty and partial tonsilectomy, showing afterwards, remission of the symptoms. We discussed the pathogenesis suggested in the literature.<\/jats:p>","DOI":"10.1590\/s0004-282x2006000300033","type":"journal-article","created":{"date-parts":[[2006,8,9]],"date-time":"2006-08-09T06:34:21Z","timestamp":1155105261000},"page":"523-525","source":"Crossref","is-referenced-by-count":12,"title":["Herniation of the cerebellar tonsils after suprasellar arachnoid cyst shunt: case report"],"prefix":"10.1590","volume":"64","author":[{"given":"Rodrigo","family":"Mendon\u00e7a","sequence":"first","affiliation":[{"name":"Hospital Cristo Redentor,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Telmo Tib\u00farcio Fortes","family":"Lima","sequence":"additional","affiliation":[{"name":"Hospital Cristo Redentor,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paulo Petry","family":"Oppitz","sequence":"additional","affiliation":[{"name":"Hospital Cristo Redentor,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S\u00e9rgio Fernando","family":"Raupp","sequence":"additional","affiliation":[{"name":"Hospital Cristo Redentor,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"530","reference":[{"key":"ref1","first-page":"167","article-title":"Cephalocranial disproportion: A complication of the treatment of hydrocephalus in children","volume":"2","author":"Hoffmann HJ","year":"1976","journal-title":"Childs Brain","ISSN":"https:\/\/id.crossref.org\/issn\/0302-2803","issn-type":"print"},{"key":"ref2","doi-asserted-by":"crossref","first-page":"800","DOI":"10.1007\/s00381-003-0837-7","article-title":"Acquired Chiari type I malformation managed by supratentorial cranial enlargement","volume":"19","author":"Di Rocco C","year":"2003","journal-title":"Childs Nerv Syst","ISSN":"https:\/\/id.crossref.org\/issn\/0256-7040","issn-type":"print"},{"key":"ref3","doi-asserted-by":"crossref","first-page":"394","DOI":"10.1007\/s003810050252","article-title":"Herniation of cerebellar tonsils following supratentorial shunt placement","volume":"14","author":"Lazareff JA","year":"1998","journal-title":"Childs Nerv Syst","ISSN":"https:\/\/id.crossref.org\/issn\/0256-7040","issn-type":"print"},{"key":"ref4","doi-asserted-by":"crossref","first-page":"126","DOI":"10.3171\/jns.1994.81.1.0126","article-title":"Hindbrain herniation: an usual occurrence after shunting an intracraninal arachnoid cyst","volume":"81","author":"Hassounah MI","year":"1994","journal-title":"J Neurosurg","ISSN":"https:\/\/id.crossref.org\/issn\/0022-3085","issn-type":"print"},{"key":"ref5","series-title":"Folia Neurobiologia Argentina Atlas I: el cerebro humano: su anatomia topografica e sistematica","first-page":"28","author":"Jakob","year":"1939"}],"container-title":["Arquivos de Neuro-Psiquiatria"],"original-title":[],"link":[{"URL":"http:\/\/www.scielo.br\/pdf\/anp\/v64n2b\/a33v642b.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,5,25]],"date-time":"2017-05-25T09:37:19Z","timestamp":1495705039000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.scielo.br\/scielo.php?script=sci_arttext&pid=S0004-282X2006000300033&lng=en&tlng=en"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2006,6]]},"references-count":5,"journal-issue":{"issue":"2b","published-print":{"date-parts":[[2006,6]]}},"alternative-id":["S0004-282X2006000300033"],"URL":"https:\/\/doi.org\/10.1590\/s0004-282x2006000300033","relation":{},"ISSN":["0004-282X"],"issn-type":[{"value":"0004-282X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2006,6]]}}}
