On examination, she was found breathless, but was not distressed or afebrile or normotensive. Auscultation of the heart revealed a positive Hamman's sign. There was chest-wall crepitus, and auscultation of the lung showed bilateral crepitations. Full blood count and biochemical profile were unremarkable. Chest x-ray showed signs of idiopathic interstitial pneumonia in addition to pneumomediastinum (linear band of air within mediastinal planes and continuous diaphragm sign) and chest-wall subcutaneous emphysema. She was treated with high-concentration oxygen. A repeat chest x-ray 5 days later showed complete resolution of the pneumomediastinum and subcutaneous emphysema, but signs of idiopathic interstitial pneumonia continued to persist.<\/jats:p>","DOI":"10.1136\/bcr.02.2010.2765","type":"journal-article","created":{"date-parts":[[2010,7,26]],"date-time":"2010-07-26T06:18:14Z","timestamp":1280125094000},"page":"bcr0220102765","source":"Crossref","is-referenced-by-count":18,"title":["Spontaneous pneumomediastinum and subcutaneous emphysema in systemic lupus erythematosus"],"prefix":"10.1136","volume":"2010","author":[{"given":"AlaEldin H","family":"Ahmed","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elrasheid A","family":"Awouda","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2010,7,26]]},"reference":[{"key":"2025082802505068000_2010.jul22_1.bcr0220102765.1","doi-asserted-by":"publisher","DOI":"10.1378\/chest.100.1.93"},{"key":"2025082802505068000_2010.jul22_1.bcr0220102765.2","doi-asserted-by":"publisher","DOI":"10.1148\/radiographics.20.4.g00jl131043"},{"key":"2025082802505068000_2010.jul22_1.bcr0220102765.3","doi-asserted-by":"crossref","first-page":"271","DOI":"10.2214\/ajr.131.2.271","article-title":"Anterior pathway for transdiaphragmatic extension of pneumomediastinum","volume":"131","author":"Kleinman","year":"1978","journal-title":"AJR Am J Roentgenol"},{"key":"2025082802505068000_2010.jul22_1.bcr0220102765.4","doi-asserted-by":"crossref","first-page":"105","DOI":"10.1007\/s10067-005-0109-x","article-title":"Spontaneous pneumomediastinum and dermatomyositis may be a not so rare association: report of a case and review of the literature","volume":"26","author":"Neves","year":"2007","journal-title":"Clin Rheumatol"},{"key":"2025082802505068000_2010.jul22_1.bcr0220102765.5","doi-asserted-by":"publisher","DOI":"10.1378\/chest.117.6.1809"},{"key":"2025082802505068000_2010.jul22_1.bcr0220102765.6","first-page":"544","article-title":"Recurrent pneumothoraces and mediastinal emphysema in systemic lupus erythematosus","volume":"17","author":"Masuda","year":"1990","journal-title":"J Rheumatol"},{"key":"2025082802505068000_2010.jul22_1.bcr0220102765.7","doi-asserted-by":"publisher","DOI":"10.1007\/BF02283123"},{"key":"2025082802505068000_2010.jul22_1.bcr0220102765.8","doi-asserted-by":"crossref","first-page":"112","DOI":"10.1097\/SMJ.0b013e31818b692e","article-title":"Pneumomediastinum in a 21-year-old female with lupus","volume":"102","author":"Koczka","year":"2009","journal-title":"South Med J"},{"key":"2025082802505068000_2010.jul22_1.bcr0220102765.9","doi-asserted-by":"publisher","DOI":"10.1159\/000194541"},{"key":"2025082802505068000_2010.jul22_1.bcr0220102765.10","doi-asserted-by":"crossref","first-page":"816","DOI":"10.1542\/peds.32.5.816","article-title":"Spontaneous alveolar rupture at birth","volume":"32","author":"Chernick","year":"1963","journal-title":"Pediatrics"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr.02.2010.2765","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,28]],"date-time":"2025-08-28T09:50:56Z","timestamp":1756374656000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr.02.2010.2765"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010]]},"references-count":10,"alternative-id":["10.1136\/bcr.02.2010.2765"],"URL":"https:\/\/doi.org\/10.1136\/bcr.02.2010.2765","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2010]]}}}
