Posterior reversible encephalopathy syndrome (PRES) is a clinicoradiologic syndrome commonly linked to acute hypertension and characterized by vasogenic edema on neuroimaging. We describe a 16\u2010year\u2010old female with a long\u2010standing, criteria\u2010based diagnosis of CVS and chronic, recurrent hypertension who developed MRI\u2010confirmed PRES during a period of sustained postoperative hypertension. She had a prior MRI\u2010confirmed episode of PRES in 2012, with documented radiologic reversibility on follow\u2010up imaging. Neuroimaging during the index admission demonstrated vasogenic edema in the parieto\u2010occipital lobes and cerebellar vermis. Secondary causes of hypertension, including pheochromocytoma, primary aldosteronism, thyroid disease, renal and renovascular disease, and Cushing syndrome, were systematically excluded, and the episode was considered most likely related to her hypertension. We discuss CVS\u2010related autonomic dysregulation as a possible contributor, while recognizing hypertension as the immediate driver of PRES in this case. Prompt antihypertensive therapy and seizure prophylaxis were followed by clinical and radiologic improvement. This case highlights the value of recognizing recurrent hypertensive PRES in adolescents with CVS and of carefully excluding alternative etiologies.<\/jats:p>","DOI":"10.1155\/crra\/3914162","type":"journal-article","created":{"date-parts":[[2026,6,26]],"date-time":"2026-06-26T07:12:50Z","timestamp":1782457970000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Recurrent PRES in a Patient With Cyclic Vomiting Syndrome"],"prefix":"10.1155","volume":"2026","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5505-2850","authenticated-orcid":false,"given":"Arman","family":"Mahmood","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8930-5681","authenticated-orcid":false,"given":"Allen","family":"Mao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4170-6483","authenticated-orcid":false,"given":"Ibrahim Sacit","family":"Tuna","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,6,26]]},"reference":[{"key":"e_1_2_9_1_2","doi-asserted-by":"publisher","DOI":"10.3389\/fneur.2020.583425"},{"key":"e_1_2_9_2_2","doi-asserted-by":"publisher","DOI":"10.1053\/j.gastro.2016.02.015"},{"key":"e_1_2_9_3_2","doi-asserted-by":"publisher","DOI":"10.1097\/MPG.0b013e31802bddb7"},{"key":"e_1_2_9_4_2","doi-asserted-by":"publisher","DOI":"10.1530\/acta.0.1170189"},{"key":"e_1_2_9_5_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00415-016-8377-8"},{"key":"e_1_2_9_6_2","doi-asserted-by":"publisher","DOI":"10.1542\/peds.2017-1904"},{"key":"e_1_2_9_7_2","doi-asserted-by":"publisher","DOI":"10.1542\/peds.2014-2325"},{"key":"e_1_2_9_8_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00381-017-3664-y"},{"key":"e_1_2_9_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.pediatrneurol.2022.06.012"},{"key":"e_1_2_9_10_2","doi-asserted-by":"publisher","DOI":"10.1136\/practneurol-2021-003194"}],"container-title":["Case Reports in Radiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1155\/crra\/3914162","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1155\/crra\/3914162","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1155\/crra\/3914162","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,6,26]],"date-time":"2026-06-26T07:12:52Z","timestamp":1782457972000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1155\/crra\/3914162"}},"subtitle":[],"editor":[{"given":"Daniel P.","family":"Link","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"editor"}]}],"short-title":[],"issued":{"date-parts":[[2026,1]]},"references-count":10,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2026,1]]}},"alternative-id":["10.1155\/crra\/3914162"],"URL":"https:\/\/doi.org\/10.1155\/crra\/3914162","archive":["Portico"],"relation":{},"ISSN":["2090-6862","2090-6870"],"issn-type":[{"value":"2090-6862","type":"print"},{"value":"2090-6870","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,1]]},"assertion":[{"value":"2025-01-16","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-06-16","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-06-26","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"3914162"}}
