CAPNON typically arises in isolation, with only two prior reports of a concurrent second neoplasm. Here, we report the case of a male 17\u2010year\u2010old who presented with new\u2010onset seizures. MRIs revealed a 2\u2009cm extra\u2010axial solid\u2010cystic mass, arising at the left temporo\u2010occipital junction and abutting the dura with marked surrounding parenchymal vasogenic edema. The solid components demonstrated dense calcification and avid enhancement. Gross total surgical resection was performed. Histopathological examination revealed central regions showing characteristic features of CAPNON. Toward the periphery, the CAPNON was intimately associated with and sharply demarcated from a meningioma, which showed up to five mitoses per 10 high\u2010power fields and had invasion into the adjacent brain parenchyma, warranting a WHO grade II designation. This is the first report of CAPNON arising in association with a meningioma. The coexistence of these two tumors raises the possibility of a reactive\/dysplastic etiology for CAPNON.<\/jats:p>","DOI":"10.1111\/neup.12500","type":"journal-article","created":{"date-parts":[[2018,7,10]],"date-time":"2018-07-10T10:06:20Z","timestamp":1531217180000},"page":"535-538","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Supratentorial CAPNON associated with WHO grade II meningioma: A case report"],"prefix":"10.1111","volume":"38","author":[{"given":"Michael A.","family":"Paolini","sequence":"first","affiliation":[{"name":"Department of Laboratory Medicine and Pathology Mayo Clinic  Rochester Minnesota USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mai\u2010Lan","family":"Ho","sequence":"additional","affiliation":[{"name":"Department of Radiology Mayo Clinic  Rochester Minnesota USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hannah R.","family":"Monahan","sequence":"additional","affiliation":[{"name":"Department of Radiology Mayo Clinic  Rochester Minnesota USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aditya","family":"Raghunathan","sequence":"additional","affiliation":[{"name":"Department of Laboratory Medicine and Pathology Mayo Clinic  Rochester Minnesota USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2018,7,10]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.clineuro.2016.02.025"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.wneu.2015.08.055"},{"key":"e_1_2_7_4_1","first-page":"231","volume-title":"WHO Classification of Tumours of the Central Nervous System","author":"Louis DN","year":"2016"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00401-007-0286-6"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.3171\/jns.1990.72.1.0042"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-200004150-00020"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.3174\/ajnr.A1505"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1227\/01.NEU.0000351770.69874.15"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.5414\/NP300360"}],"container-title":["Neuropathology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fneup.12500","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/neup.12500","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,9,17]],"date-time":"2023-09-17T06:56:27Z","timestamp":1694933787000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/neup.12500"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,7,10]]},"references-count":9,"journal-issue":{"issue":"5","published-print":{"date-parts":[[2018,10]]}},"alternative-id":["10.1111\/neup.12500"],"URL":"https:\/\/doi.org\/10.1111\/neup.12500","archive":["Portico"],"relation":{},"ISSN":["0919-6544","1440-1789"],"issn-type":[{"value":"0919-6544","type":"print"},{"value":"1440-1789","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018,7,10]]},"assertion":[{"value":"2018-01-29","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2018-06-12","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2018-07-10","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
