PNMD may cause a wide variety of signs and symptoms, as well as ECG abnormality, including ST segment changes. We present a 56-year-old man admitted to our hospital after a <jats:italic>facial<\/jats:italic> trauma. After undergoing tracheostomy, he complained of chest discomfort. A chest X-ray in the posteroanterior view showed PNMD, and an ECG was suggestive of inferior-lateral wall myocardial infarction. An urgent cardiac catheterisation identified a critical obstruction at the origin of the right coronary artery. Following a balloon angioplasty, chest discomfort continued; and the ECG ST segments did not show any dynamic change during the subsequent 72\u2009hours. We urge clinicians to perform a comprehensive workup for every patient presenting with PNMD and ST segment changes, to prevent unnecessary invasive procedures.<\/jats:p>","DOI":"10.1136\/bcr-2018-227932","type":"journal-article","created":{"date-parts":[[2019,2,7]],"date-time":"2019-02-07T04:38:07Z","timestamp":1549514287000},"page":"bcr-2018-227932","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":5,"title":["Pneumomediastinum, ST elevation and urgent cardiac catheterisation: a crucial triad?"],"prefix":"10.1136","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4162-8406","authenticated-orcid":false,"given":"Amit","family":"Frenkel","sequence":"first","affiliation":[{"name":"General Intensive Care Unit, Soroka University Medical Center and the Faculty of Health Sciences, Ben-Gurion University of the Negev, Beer-Sheva, Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yair","family":"Binyamin","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, Soroka University Medical Center and the Faculty of Health Sciences, Ben-Gurion University of the Negev, Beer-Sheva, Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vladimir","family":"Zeldetz","sequence":"additional","affiliation":[{"name":"Emergency Medicine Departemt, Soroka University Medical Center and the Faculty of Health Sciences, Ben-Gurion University of the Negev, Beer-Sheva, Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Leonid","family":"Koyfman","sequence":"additional","affiliation":[{"name":"General Intensive Care Unit, Soroka University Medical Center and the Faculty of Health Sciences, Ben-Gurion University of the Negev, Beer-Sheva, Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Moti","family":"Klein","sequence":"additional","affiliation":[{"name":"General Intensive Care Unit, Soroka University Medical Center and the Faculty of Health Sciences, Ben-Gurion University of the Negev, Beer-Sheva, Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Evgeni","family":"Brotfain","sequence":"additional","affiliation":[{"name":"General Intensive Care Unit, Soroka University Medical Center and the Faculty of Health Sciences, Ben-Gurion University of the Negev, Beer-Sheva, Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2019,2,6]]},"reference":[{"key":"2025082700373871000_12.2.bcr-2018-227932.1","first-page":"1","article-title":"Pneumomediastinum and Mediastinal Hematoma Secondary to Right Brachiocephalic Vein Thrombectomy Mimicking STEMI","volume":"2017","author":"Shukla","year":"2017","journal-title":"Case Rep Cardiol"},{"key":"2025082700373871000_12.2.bcr-2018-227932.2","doi-asserted-by":"publisher","DOI":"10.1378\/chest.86.1.143"},{"key":"2025082700373871000_12.2.bcr-2018-227932.3","doi-asserted-by":"crossref","first-page":"682","DOI":"10.1097\/00000441-194612000-00004","article-title":"Electrocardiographic phenomena associated with spontaneous pneumothorax and mediastinal emphysema","volume":"212","author":"Littmann","year":"1946","journal-title":"Am J Med Sci"},{"key":"2025082700373871000_12.2.bcr-2018-227932.4","doi-asserted-by":"crossref","first-page":"1603","DOI":"10.1016\/j.amjcard.2016.08.032","article-title":"Pneumomediastinum and ST-Segment Elevation","volume":"118","author":"Lolay","year":"2016","journal-title":"Am J Cardiol"},{"key":"2025082700373871000_12.2.bcr-2018-227932.5","doi-asserted-by":"publisher","DOI":"10.1016\/j.hrtlng.2010.09.007"},{"key":"2025082700373871000_12.2.bcr-2018-227932.6","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijcard.2006.11.156"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2018-227932","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T07:37:48Z","timestamp":1756280268000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2018-227932"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,2]]},"references-count":6,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2019,2,6]]},"published-print":{"date-parts":[[2019,2]]}},"alternative-id":["10.1136\/bcr-2018-227932"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2018-227932","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,2]]}}}
