We highlight the potential utility of non-contrast CT for detection of aortic dissection in a case of a young, immunocompromised man presenting with acute abdominal pain and renal injury. Given elevated creatinine, an initial non-contrast chest CT demonstrated subtle findings suggestive of aortic dissection (aneurysmal dilation of the proximal ascending aorta as well as displaced calcified intimal flap\/ intraluminal high linear density in the thoracic descending and distal abdominal aorta). Subsequent CT angiography confirmed the presence of an extensive type A aortic dissection. He underwent emergent exploratory laparotomy and hemiarch repair. Displaced calcified intimal flaps, intraluminal high-densities, intramural hematoma, and aneurysmal aortic dilation are common non-contrast computed tomography imaging findings that suggest aortic dissection.<\/jats:p>","DOI":"10.55729\/2000-9666.1178","type":"journal-article","created":{"date-parts":[[2023,5,11]],"date-time":"2023-05-11T06:23:06Z","timestamp":1683786186000},"source":"Crossref","is-referenced-by-count":4,"title":["Type A Aortic Dissection and Non-Contrast Computed Tomography"],"prefix":"10.55729","volume":"13","author":[{"given":"Amelie","family":"Spangenberg","sequence":"first","affiliation":[{"name":"MedStar Health Internal Medicine Residency Program, MedStar Union Memorial Hospital, 201 E University Pkwy, Baltimore, MD 21218, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shiavax J.","family":"Rao","sequence":"additional","affiliation":[{"name":"MedStar Health Internal Medicine Residency Program, MedStar Union Memorial Hospital, 201 E University Pkwy, Baltimore, MD 21218, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John","family":"Mackrell","sequence":"additional","affiliation":[{"name":"Department of Radiology, MedStar MedStar Franklin Square Medical Center, 9000 Franklin Square Drive, Baltimore, MD 21237, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarah","family":"Rimm","sequence":"additional","affiliation":[{"name":"Department of Emergency Medicine, MedStar Franklin Square Medical Center, 9000 Franklin Square Drive, Baltimore, MD 21237, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher James","family":"Haas","sequence":"additional","affiliation":[{"name":"Georgetown University School of Medicine, Washington, DC, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"34701","published-online":{"date-parts":[[2023,5,10]]},"container-title":["Journal of Community Hospital Internal Medicine Perspectives"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/scholarlycommons.gbmc.org\/cgi\/viewcontent.cgi?article=1178&amp;context=jchimp","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,9,5]],"date-time":"2026-09-05T10:01:51Z","timestamp":1788602511000},"score":1,"resource":{"primary":{"URL":"https:\/\/scholarlycommons.gbmc.org\/jchimp\/vol13\/iss3\/23"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,5,10]]},"references-count":0,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2023,5,10]]}},"URL":"https:\/\/doi.org\/10.55729\/2000-9666.1178","relation":{},"ISSN":["2000-9666"],"issn-type":[{"value":"2000-9666","type":"electronic"}],"subject":[],"published":{"date-parts":[[2023,5,10]]}}}
