On examination, there was surgical emphysema. A CT scan confirmed air in the subcutaneous tissues and also revealed pneumomediastinum. There was no evidence of pneumothorax and gastro-oesophageal endoscopy showed no signs of oesophageal rupture. The patient remained clinically stable throughout her admission and was discharged home after 48\u2009hours of observation. Pneumomediastinum is one of the rare causes of shortness of breath and chest pain during the postpartum period, and it should be considered in the differential diagnosis. Despite the significant abnormalities seen on plain radiography and CT scan, this condition spontaneously resolves. Although postpartum pneumomediastinum has been related to prolonged labour, this was not the case in our patient.<\/jats:p>","DOI":"10.1136\/bcr-2018-224800","type":"journal-article","created":{"date-parts":[[2018,5,18]],"date-time":"2018-05-18T09:30:27Z","timestamp":1526635827000},"page":"bcr-2018-224800","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":3,"title":["Postpartum pneumomediastinum and subcutaneous emphysema"],"prefix":"10.1136","volume":"2018","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9732-4578","authenticated-orcid":false,"given":"Diaeddin","family":"Sagar","sequence":"first","affiliation":[{"name":"Respiratory Department, Doncaster and Bassetlaw Teaching Hospitals NHS Foundation Trust, Doncaster, UK"},{"name":"Respiratory Department, Sheffield Teaching Hospitals, Sheffield, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Trevor K","family":"Rogers","sequence":"additional","affiliation":[{"name":"Respiratory Medicine, Doncaster and Bessetlaw Teaching Hospitals NHS Foundation Trust, Doncaster, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aldrin","family":"Adeni","sequence":"additional","affiliation":[{"name":"Respiratory Department, Doncaster and Bessetlaw Teaching Hospitals NHS Foundation Trust, Doncaster, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2018,5,18]]},"reference":[{"key":"2025082801463037000_2018.may16_1.bcr-2018-224800.1","doi-asserted-by":"publisher","DOI":"10.1001\/jama.1945.02860180003001"},{"key":"2025082801463037000_2018.may16_1.bcr-2018-224800.2","doi-asserted-by":"crossref","unstructured":"Segev T , Thor JA , Lentz J , et al .
