Neuroradiological features showed a mass surrounding the ventricular catheter. The lesion was completely resected. Histological study revealed the mass to be an IMT. The patient's postoperative course was complicated by a local recurrence requiring a second surgery. Cytogenetic analysis of the sample by comparative genome hybridization revealed several chromosomal amplifications and regional losses. The occurrence of IMT in the CNS has rarely been reported. For treatment of this condition, the authors recommend a total removal of the shunt with a mass excision to prevent local recurrence.<\/jats:p>","DOI":"10.3171\/2009.5.peds0958","type":"journal-article","created":{"date-parts":[[2009,10,1]],"date-time":"2009-10-01T16:05:27Z","timestamp":1254413127000},"page":"372-377","source":"Crossref","is-referenced-by-count":8,"title":["Clinical and cytogenetic analysis of an intracranial inflammatory myofibroblastic tumor induced by a ventriculoperitoneal shunt"],"prefix":"10.3171","volume":"4","author":[{"given":"Ricardo Santos","family":"de Oliveira","sequence":"first","affiliation":[{"name":"Division of Pediatric Neurosurgery, Department of Surgery and Anatomy;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marcelo Campos Moraes","family":"Amato","sequence":"additional","affiliation":[{"name":"Division of Pediatric Neurosurgery, Department of Surgery and Anatomy;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mar\u00eda Sol","family":"Brassesco","sequence":"additional","affiliation":[{"name":"Division of Pediatric Oncology, Department of Pediatrics; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elvis Terci","family":"Valera","sequence":"additional","affiliation":[{"name":"Division of Pediatric Oncology, Department of Pediatrics; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carlos Eduardo Barros","family":"Juc\u00e1","sequence":"additional","affiliation":[{"name":"Division of Pediatric Neurosurgery, Department of Surgery and Anatomy;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luciano","family":"Neder","sequence":"additional","affiliation":[{"name":"Department of Pathology, Faculty of Medicine of Ribeir\u00e3o Preto, University of S\u00e3o Paulo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luiz Gonzaga","family":"Tone","sequence":"additional","affiliation":[{"name":"Division of Pediatric Oncology, Department of Pediatrics; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H\u00e9lio Rubens","family":"Machado","sequence":"additional","affiliation":[{"name":"Division of Pediatric Neurosurgery, Department of Surgery and Anatomy;"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1-0040372","series-title":"Histopathology","first-page":"98","article-title":"Plasma cell granuloma of central nervous system","volume":"12","author":"Aozasa","year":"1988"},{"key":"b2-0040372","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"975","DOI":"10.3171\/jns.1998.88.6.0975","article-title":"Mechanical dysfunction of ventriculoperitoneal shunts caused by calcification of the silicone rubber catheter","volume":"88","author":"Boch","year":"1998"},{"key":"b3-0040372","series-title":"Lung","doi-asserted-by":"publisher","first-page":"355","DOI":"10.1007\/s00408-006-0009-0","article-title":"Comparative genomic hybridization array analysis and realtime PCR reveals genomic copy number alteration for lung adenocarcinomas","volume":"184","author":"Choi","year":"2006"},{"key":"b4-0040372","series-title":"Comput Tomogr","doi-asserted-by":"publisher","first-page":"177","DOI":"10.1016\/0363-8235(79)90029-2","article-title":"Computed tomographic presentation of granulomatous reaction from intraventricular shunt","volume":"3","author":"Citrin","year":"1979"},{"key":"b5-0040372","series-title":"Mod Pathol","doi-asserted-by":"publisher","first-page":"569","DOI":"10.1038\/modpathol.3880352","article-title":"ALK1 and p80 expression and chromosomal rearrangements involving 2p23 in inflammatory myofibroblastic tumor","volume":"14","author":"Coffin","year":"2001"},{"key":"b6-0040372","series-title":"Neurosurgery","doi-asserted-by":"publisher","first-page":"319","DOI":"10.1097\/00006123-199802000-00064","article-title":"Biological reactions to cerebrospinal fluid shunt devices: a review of the cellular biology","volume":"42","author":"Del Bigio","year":"1998"},{"key":"b7-0040372","series-title":"Neurochirurgie","first-page":"325","article-title":"[Intracranial granuloma: a rare complication of ventricular derivation.
