He also had shortness of breath with right-sided pleuritic chest pain. On examination he was found to have a rigid and diffusely tender abdomen. Auscultation of the chest revealed reduced air entry into the right lung. An erect chest X-ray confirmed the presence of pneumoperitoneum and a right-sided pneumothorax. He underwent placement of a right intercostal drain followed by urgent laparotomy. The intraoperative findings were consistent with a small duodenal perforation, which was managed by a simple omental patch closure. His postoperative course was uneventful. Pneumothorax is a rare complication of perforated duodenal ulcer and should be kept in mind while assessing patients who present with abdominal pain and dyspnoea. We have discussed various possibilities that should be considered in patients who present with a concomitant pneumothorax and pneumoperitoneum.<\/jats:p>","DOI":"10.1136\/bcr-2013-201370","type":"journal-article","created":{"date-parts":[[2014,4,3]],"date-time":"2014-04-03T10:48:24Z","timestamp":1396522104000},"page":"bcr2013201370","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Pneumothorax as a presentation of perforated duodenal ulcer"],"prefix":"10.1136","volume":"2014","author":[{"given":"Shihab Ahmed","family":"Mahdi","sequence":"first","affiliation":[{"name":"Rashid Hospital Trauma Center, Dubai Health Authority, Dubai, United Arab Emirates"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Firas Jaafar","family":"Kareem AlNajjar","sequence":"additional","affiliation":[{"name":"Rashid Hospital Trauma Center, Dubai Health Authority, Dubai, United Arab Emirates"},{"name":"Emergency Medicine, Dubai Residency Training Program, Dubai Health Authority, Dubai, United Arab Emirates"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kosar","family":"Hussain","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Rashid Hospital, Dubai Health Authority, Dubai, United Arab Emirates"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2014,4,3]]},"reference":[{"key":"2025082702082310000_2014.apr03_1.bcr2013201370.1","doi-asserted-by":"publisher","DOI":"10.1164\/rccm.201205-0940IM"},{"key":"2025082702082310000_2014.apr03_1.bcr2013201370.2","first-page":"233","article-title":"Barotrauma-induced tension pneumoperitoneum","volume":"54","author":"Canivet","year":"2003","journal-title":"Acta Anaesthesiol Belg"},{"key":"2025082702082310000_2014.apr03_1.bcr2013201370.3","doi-asserted-by":"publisher","DOI":"10.1089\/lap.2008.0287"},{"key":"2025082702082310000_2014.apr03_1.bcr2013201370.4","doi-asserted-by":"publisher","DOI":"10.1093\/jscr\/2011.5.5"},{"key":"2025082702082310000_2014.apr03_1.bcr2013201370.5","doi-asserted-by":"publisher","DOI":"10.1016\/S0221-0363(04)97682-2"},{"key":"2025082702082310000_2014.apr03_1.bcr2013201370.6","first-page":"703","article-title":"Pneumomediastinum, pneumothorax, and subcutaneous emphysema due to duodenal ulcer","volume":"31","author":"Abdullah","year":"2010","journal-title":"Saudi Med J"},{"key":"2025082702082310000_2014.apr03_1.bcr2013201370.7","doi-asserted-by":"crossref","first-page":"344","DOI":"10.1080\/00015458.2006.11679903","article-title":"Duodenal ulcer perforation and pneumothorax: a case report.","volume":"106","author":"Basak","year":"2006","journal-title":"Acta Chir Belg"},{"key":"2025082702082310000_2014.apr03_1.bcr2013201370.8","doi-asserted-by":"publisher","DOI":"10.1016\/j.gie.2008.03.007"},{"key":"2025082702082310000_2014.apr03_1.bcr2013201370.9","first-page":"462","article-title":"Bilateral tension pneumothoraces and subcutaneous emphysema following colonoscopic polypectomy: a case report and discussion of anesthesia considerations","volume":"78","author":"Kipple","year":"2010","journal-title":"AANA J"},{"key":"2025082702082310000_2014.apr03_1.bcr2013201370.10","doi-asserted-by":"crossref","first-page":"W20","DOI":"10.1308\/147870807X188506","article-title":"Pneumothorax, pneumomediastinum, pneumoperitoneum, pneumoretroperitoneum and subcutaneous emphysema following diagnostic colonoscopy","volume":"89","author":"Marwan","year":"2007","journal-title":"Ann R Coll Surg Engl"},{"key":"2025082702082310000_2014.apr03_1.bcr2013201370.11","doi-asserted-by":"publisher","DOI":"10.1097\/00000441-200609000-00012"},{"key":"2025082702082310000_2014.apr03_1.bcr2013201370.12","doi-asserted-by":"publisher","DOI":"10.1055\/s-2007-1004205"},{"key":"2025082702082310000_2014.apr03_1.bcr2013201370.13","doi-asserted-by":"publisher","DOI":"10.1055\/s-2002-36471"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2013-201370","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T09:08:35Z","timestamp":1756285715000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2013-201370"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014,4,3]]},"references-count":13,"alternative-id":["10.1136\/bcr-2013-201370"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2013-201370","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2014,4,3]]}}}
