Due to its persistence in the subarachnoid space and the potential to lead to severe arachnoiditis, it is no longer used today. We present a 40\u2010year\u2010old male with new\u2010onset headaches, imbalance, and vertigo. Brain magnetic resonance imaging revealed a 2\u2010mm T1 \u2010hyperintense intracanalicular lesion. Numerous hyperdense foci were scattered throughout the subarachnoid space on computed tomography. Further history revealed the patient received Pantopaque 30 years prior, after sustaining spinal trauma. Remnant Pantopaque contrast is an important differential when evaluating a patient with a suspected intracranial tumor in order to avoid unwarranted surgical intervention. <jats:italic>Laryngoscope<\/jats:italic>, 127:1916\u20131919, 2017<\/jats:p>","DOI":"10.1002\/lary.26340","type":"journal-article","created":{"date-parts":[[2016,10,13]],"date-time":"2016-10-13T13:42:57Z","timestamp":1476366177000},"page":"1916-1919","source":"Crossref","is-referenced-by-count":3,"title":["Pantopaque contrast mimicking intracanalicular vestibular schwannoma"],"prefix":"10.1002","volume":"127","author":[{"given":"Nicholas L.","family":"Deep","sequence":"first","affiliation":[{"name":"Department of Otorhinolaryngology Mayo Clinic Phoenix Arizona U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ameet C.","family":"Patel","sequence":"additional","affiliation":[{"name":"Neuroradiology Division, Department of Radiology Mayo Clinic Phoenix Arizona U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joseph M.","family":"Hoxworth","sequence":"additional","affiliation":[{"name":"Neuroradiology Division, Department of Radiology Mayo Clinic Phoenix Arizona U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David M.","family":"Barrs","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology Mayo Clinic Phoenix Arizona U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2016,10,11]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1259\/0007-1285-65-780-1105"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1227\/00006123-198003000-00018"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-198307000-00011"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1440-1673.2001.00911.x"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.3171\/SPI\/2008\/8\/3\/292"},{"key":"e_1_2_5_7_1","doi-asserted-by":"publisher","DOI":"10.1097\/00004728-198803000-00033"},{"key":"e_1_2_5_8_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00586-012-2364-2"},{"key":"e_1_2_5_9_1","first-page":"997","article-title":"The behavior of Pantopaque on MR: in vivo and in vitro analysis","volume":"7","author":"Braun IF","year":"1986","journal-title":"AJNR Am J Neuroradiol"},{"key":"e_1_2_5_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/0730-4862(87)90045-X"},{"key":"e_1_2_5_11_1","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.168.2.9016253"}],"container-title":["The Laryngoscope"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Flary.26340","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Flary.26340","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/lary.26340","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,9,9]],"date-time":"2023-09-09T15:10:34Z","timestamp":1694272234000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/lary.26340"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016,10,11]]},"references-count":10,"journal-issue":{"issue":"8","published-print":{"date-parts":[[2017,8]]}},"alternative-id":["10.1002\/lary.26340"],"URL":"https:\/\/doi.org\/10.1002\/lary.26340","archive":["Portico"],"relation":{},"ISSN":["0023-852X","1531-4995"],"issn-type":[{"value":"0023-852X","type":"print"},{"value":"1531-4995","type":"electronic"}],"subject":[],"published":{"date-parts":[[2016,10,11]]}}}
