Postoperative chemotherapy is the recommended first-line treatment when gross-total removal is not achieved or in cases of disseminated disease. Here the authors report on 2 children with atypical choroid plexus papillomas and MRI findings of diffuse leptomeningeal enhancement at diagnosis, later presenting with spontaneous resolution of the leptomeningeal involvement after removal of the primary lesions. Observations in this report expand our knowledge about the natural history and biological behavior of these tumors and highlight the role of close neuroimaging surveillance in the management of atypical choroid plexus papillomas in cases with MRI evidence of diffuse leptomeningeal enhancement at presentation.<\/jats:p>","DOI":"10.3171\/2017.2.peds16526","type":"journal-article","created":{"date-parts":[[2017,7,7]],"date-time":"2017-07-07T10:02:01Z","timestamp":1499421721000},"page":"284-288","source":"Crossref","is-referenced-by-count":11,"title":["Atypical choroid plexus papilloma: spontaneous resolution of diffuse leptomeningeal contrast enhancement after primary tumor removal in 2 pediatric cases"],"prefix":"10.3171","volume":"20","author":[{"given":"Marcello","family":"Scala","sequence":"first","affiliation":[{"name":"Neuro-Oncology Unit,"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giovanni","family":"Morana","sequence":"additional","affiliation":[{"name":"Neuroradiology Unit, and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claudia","family":"Milanaccio","sequence":"additional","affiliation":[{"name":"Neuro-Oncology Unit,"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marco","family":"Pavanello","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paolo","family":"Nozza","sequence":"additional","affiliation":[{"name":"Pathology, Istituto Giannina Gaslini, Genova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria Luisa","family":"Garr\u00e8","sequence":"additional","affiliation":[{"name":"Neuro-Oncology Unit,"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Surg Neurol","doi-asserted-by":"publisher","first-page":"54","DOI":"10.1016\/0090-3019(91)90134-U","article-title":"Intracranial metastasis of a choroid plexus papilloma originating in the cerebellopontine angle region: a case report","volume":"36","author":"Enomoto H","year":"1991","unstructured":"Enomoto H, Mizuno M, Katsumata T, Doi T: Intracranial metastasis of a choroid plexus papilloma originating in the cerebellopontine angle region: a case report.
