The phenomenon is caused by blood-brain barrier disruption following acute reperfusion and consecutive delayed gadolinium enhancement in the subarachnoid space on fluid attenuated inversion recovery (FLAIR) images. Here we report the case of an 80-year-old man who presented with transient paresis and sensory loss in the right arm. Initial routine stroke MRI including diffusion- and perfusion-weighted imaging demonstrated no acute pathology. Follow-up MRI after three hours demonstrated subarachnoid gadolinium enhancement in the left middle cerebral artery territory consistent with HARM that completely resolved on follow-up MRI three days later. This case illustrates that even in transient ischemic attack patients disturbances of the blood-brain barrier may be present which significantly exceed the extent of acute ischemic lesions on diffusion-weighted imaging. Inclusion of FLAIR images with delayed acquisition after intravenous contrast agent application in MRI stroke protocols might facilitate the diagnosis of a recent acute ischemic stroke.<\/jats:p>","DOI":"10.1155\/2016\/9829823","type":"journal-article","created":{"date-parts":[[2016,4,3]],"date-time":"2016-04-03T17:01:29Z","timestamp":1459702889000},"page":"1-4","source":"Crossref","is-referenced-by-count":5,"title":["Hyperintense Acute Reperfusion Marker on FLAIR in a Patient with Transient Ischemic Attack"],"prefix":"10.1155","volume":"2016","author":[{"given":"Alex","family":"F\u00f6rster","sequence":"first","affiliation":[{"name":"Department of Neuroradiology, University Hospital Mannheim, University of Heidelberg, Theodor-Kutzer-Ufer 1-3, 68167 Mannheim, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Holger","family":"Wenz","sequence":"additional","affiliation":[{"name":"Department of Neuroradiology, University Hospital Mannheim, University of Heidelberg, Theodor-Kutzer-Ufer 1-3, 68167 Mannheim, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christoph","family":"Groden","sequence":"additional","affiliation":[{"name":"Department of Neuroradiology, University Hospital Mannheim, University of Heidelberg, Theodor-Kutzer-Ufer 1-3, 68167 Mannheim, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"98","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1002\/ana.24026"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.0000141703.21173.91"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1016\/j.neurad.2012.02.002"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1016\/j.jstrokecerebrovasdis.2014.12.037"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1159\/000333286"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1002\/ana.20199"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1161\/01.str.0000144051.32131.09"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1097\/00004728-199211000-00001"},{"issue":"4","key":"9","first-page":"648","volume":"24","year":"2003","journal-title":"American Journal of Neuroradiology"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1161\/strokeaha.111.632356"},{"issue":"1","key":"11","first-page":"105","volume":"21","year":"2000","journal-title":"American Journal of Neuroradiology"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1212\/wnl.0b013e318236ef46"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1212\/wnl.0000000000001587"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1212\/nxi.0000000000000164"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1161\/strokeaha.109.570515"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1007\/s00330-010-1881-9"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.3348\/kjr.2015.16.4.906"},{"key":"18","doi-asserted-by":"publisher","DOI":"10.3174\/ajnr.a3251"},{"key":"19","doi-asserted-by":"publisher","DOI":"10.1007\/s00270-010-0035-4"},{"key":"20","doi-asserted-by":"publisher","DOI":"10.1212\/01.wnl.0000340983.00152.69"}],"container-title":["Case Reports in Radiology"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/crira\/2016\/9829823.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/crira\/2016\/9829823.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/crira\/2016\/9829823.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2016,8,18]],"date-time":"2016-08-18T23:56:52Z","timestamp":1471564612000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/crira\/2016\/9829823\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016]]},"references-count":20,"alternative-id":["9829823","9829823"],"URL":"https:\/\/doi.org\/10.1155\/2016\/9829823","relation":{},"ISSN":["2090-6862","2090-6870"],"issn-type":[{"value":"2090-6862","type":"print"},{"value":"2090-6870","type":"electronic"}],"subject":[],"published":{"date-parts":[[2016]]}}}
