A mimic is intramural blood pool with is a small contrast focus in an intramural hematoma associated with the origin of a small side branch entering the aorta. The most common accepted pathogenesis theory is that intramural hematomas arise from spontaneous rupture of the vasa vasorium.\u003c/p\u003e\u003cp\u003eThe false statement is 'are hypodense to the aortic lumen on non-contrast CT'. On non-contrast CT IMHs are \u003cstrong\u003ehyperdense\u003c/strong\u003e compared to the aortic lumen, hence the need to perform initial non-contrast imaging.\u003c/p\u003e","id":2016,"imageUrl":null,"imageAttribution":null,"imageAttributionCaseInfo":null,"firstQuestionPath":"/questions/2017","nextQuestionPath":"/articles/acute-aortic-syndrome/questions/2015","relatedArticles":[{"id":919,"title":"Aortic intramural hematoma","link":"/articles/aortic-intramural-haematoma?lang=us"},{"id":2081,"title":"Stanford classification of aortic dissection","link":"/articles/stanford-classification-of-aortic-dissection-1?lang=us"},{"id":88793,"title":"Intramural blood pool (aorta)","link":"/articles/intramural-blood-pool-aorta?lang=us"}],"alsoUsedIn":[{"id":988,"kind":"Course","title":"2021 Virtual Conference Private Use - page 988","link":"https://radiopaedia.org/courses/2021-virtual-conference-private-use/pages/988"},{"id":988,"kind":"Course","title":"Radiopaedia 2021 - isoCME - page 988","link":"https://radiopaedia.org/courses/radiopaedia-2021-isocme/pages/988"},{"id":988,"kind":"Course","title":"2022 Virtual Conference Private Use - page 988","link":"https://radiopaedia.org/courses/2022-virtual-conference-private-use/pages/988"},{"id":970,"kind":"RestrictedPage","title":"Page 970 (in no courses)","link":"https://radiopaedia.org/admin/restricted_pages/970"},{"id":955,"kind":"RestrictedPage","title":"Page 955 (in no courses)","link":"https://radiopaedia.org/admin/restricted_pages/955"},{"id":1,"kind":"LiveSchedule","title":"1","link":"https://radiopaedia.org/admin/live_schedules/1"},{"id":23,"kind":"LiveSchedule","title":"23","link":"https://radiopaedia.org/admin/live_schedules/23"},{"id":1352,"kind":"Course","title":"2022 Virtual Conference Private Use - page 1352","link":"https://radiopaedia.org/courses/2022-virtual-conference-private-use/pages/1352"},{"id":1200,"kind":"Course","title":"2022 Virtual Conference Private Use - page 1200","link":"https://radiopaedia.org/courses/2022-virtual-conference-private-use/pages/1200"},{"id":248,"kind":"LiveSchedule","title":"248","link":"https://radiopaedia.org/admin/live_schedules/248"},{"id":165,"kind":"LiveSchedule","title":"165","link":"https://radiopaedia.org/admin/live_schedules/165"},{"id":948,"kind":"Course","title":"Radiopaedia 2021 - isoCME - page 948","link":"https://radiopaedia.org/courses/radiopaedia-2021-isocme/pages/948"},{"id":948,"kind":"Course","title":"2021 Virtual Conference Private Use - page 948","link":"https://radiopaedia.org/courses/2021-virtual-conference-private-use/pages/948"},{"id":948,"kind":"Course","title":"Chest Lectures - page 948","link":"https://radiopaedia.org/courses/chest-lectures/pages/948"},{"id":1206,"kind":"Course","title":"2022 Virtual Conference Private Use - page 1206","link":"https://radiopaedia.org/courses/2022-virtual-conference-private-use/pages/1206"}],"stem":"\u003cp\u003eWhich statement regarding aortic intramural hematoma\u0026nbsp;(IMH) is\u0026nbsp;\u003cstrong\u003eFALSE\u003c/strong\u003e?\u003c/p\u003e","menuLinks":[{"text":"Report problem with question","url":"https://docs.google.com/forms/d/e/1FAIpQLSfO3soWYhOjJ7yErSysyCe5V4A1CqW7WK3rDA7MtAkecMGqNw/viewform?entry.1624461248\u0026entry.553583435=https://radiopaedia.org/questions/2016"}],"attemptsPercentages":[{"alternativeId":"10029","percentage":12},{"alternativeId":"10031","percentage":5},{"alternativeId":"10032","percentage":4},{"alternativeId":"10030","percentage":8},{"alternativeId":"10033","percentage":72}],"promptToLogin":false,"questionManager":false,"articleId":"acute-aortic-syndrome"}
