However, there are few case reports of postmortem imaging of dialysis patients. Here, we report a fatal case of gas gangrene involving a 76-year-old man who underwent dialysis. He died suddenly before a diagnosis could be established. Immediately after his death, postmortem computed tomography (PMCT) revealed gas accumulation in his right upper extremity and ascending aorta. Gas gangrene progresses rapidly and may sometimes result in sudden death before it is diagnosed. In this case, PMCT findings were useful to diagnose gas gangrene. Intravascular gas is a common finding on PMCT and is generally caused by cardiopulmonary resuscitation and decomposition. However, the detection of gas in the ascending aorta by PMCT was not described previously. Moreover, Gram stain and culture of the exudate showed anaerobic Gram-positive bacilli which suggested that the gas generation in the blood was caused by <jats:italic>Clostridia<\/jats:italic> species. To the best our knowledge, this is the first report of a dialysis patient whose cause of death was determined as gas gangrene using PMCT.<\/jats:p>","DOI":"10.1007\/s13730-020-00456-y","type":"journal-article","created":{"date-parts":[[2020,4,22]],"date-time":"2020-04-22T04:02:40Z","timestamp":1587528160000},"page":"308-312","update-policy":"http:\/\/dx.doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Postmortem computed tomography of gas gangrene with aortic gas in a dialysis patient"],"prefix":"10.1007","volume":"9","author":[{"given":"Rin","family":"Asao","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazumasa","family":"Nishida","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiromichi","family":"Goto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshikazu","family":"Goto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Noriatsu","family":"Ichiba","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Isao","family":"Ohsawa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2020,4,22]]},"reference":[{"issue":"10","key":"456_CR1","doi-asserted-by":"publisher","first-page":"2253","DOI":"10.1056\/NEJMra1600673","volume":"377","author":"DL Stevens","year":"2017","unstructured":"Stevens DL, Bryant AE.
