Elevated intracranial pressure (ICP) can result from a variety of inflammatory and structural causes affecting cerebrospinal fluid production and absorption. First described in 1935, syphilis is a well-established cause of elevated ICP, referred to as syphilitic hydrocephalus. We report a case of a 49-year-old man presenting with vision changes and headache who was treated for IIH without resolution of symptoms, and eventually diagnosed with syphilitic hydrocephalus. Syphilis should be considered as a cause of elevated ICP prior to a diagnosis of IIH.<\/jats:p>","DOI":"10.1177\/0956462420943017","type":"journal-article","created":{"date-parts":[[2020,8,5]],"date-time":"2020-08-05T02:44:28Z","timestamp":1596595468000},"page":"1117-1119","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["More than meets the eye: Papilledema from syphilis posing as idiopathic intracranial hypertension"],"prefix":"10.1177","volume":"31","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6081-5696","authenticated-orcid":false,"given":"Sharon","family":"Chi","sequence":"first","affiliation":[{"name":"School of Medicine and Health Sciences, The George Washington University, Washington, DC, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amy","family":"Weintrob","sequence":"additional","affiliation":[{"name":"School of Medicine and Health Sciences, The George Washington University, Washington, DC, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2020,8,4]]},"reference":[{"key":"bibr1-0956462420943017","doi-asserted-by":"publisher","DOI":"10.1055\/s-0039-1688942"},{"key":"bibr2-0956462420943017","doi-asserted-by":"publisher","DOI":"10.1016\/0022-510X(88)90220-1"},{"key":"bibr3-0956462420943017","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-109-11-855"},{"key":"bibr4-0956462420943017","doi-asserted-by":"publisher","DOI":"10.1097\/00005792-193502000-00003"},{"key":"bibr5-0956462420943017","doi-asserted-by":"publisher","DOI":"10.1017\/S0317167100033035"},{"key":"bibr6-0956462420943017","doi-asserted-by":"publisher","DOI":"10.1136\/bcr.09.2011.4813"},{"key":"bibr7-0956462420943017","doi-asserted-by":"publisher","DOI":"10.1001\/archneur.1987.00520170005007"},{"key":"bibr8-0956462420943017","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.0b013e3182a55f17"},{"key":"bibr9-0956462420943017","doi-asserted-by":"publisher","DOI":"10.1212\/01.WNL.0000029570.69134.1B"},{"key":"bibr10-0956462420943017","doi-asserted-by":"publisher","DOI":"10.1128\/JCM.00310-17"},{"key":"bibr11-0956462420943017","unstructured":"Centers for Disease Control.
