Its incidence is higher in preterm infants and those on positive airway pressure support or on mechanical ventilation. But it has decreased dramatically after the introduction of surfactant and synchronized, non-invasive mechanical ventilation. Underlying cystic lesions could also increase the risk of pneumomediastinum and other air leak syndromes. Most cases resolve spontaneously but rare hemodynamic compromise may require ultrasound-guided intervention.<\/jats:p>","DOI":"10.3390\/children6090104","type":"journal-article","created":{"date-parts":[[2019,9,23]],"date-time":"2019-09-23T04:50:21Z","timestamp":1569214221000},"page":"104","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Pneumomediastinum Mimicking Congenital Pulmonary Airway Malformation"],"prefix":"10.3390","volume":"6","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9666-6883","authenticated-orcid":false,"given":"Ranjit I","family":"Kylat","sequence":"first","affiliation":[{"name":"Department of Pediatrics, College of Medicine, University of Arizona, PO BOX 245073, 1501 N Campbell Avenue, Tucson, AZ 85724, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,9,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"197","DOI":"10.1016\/S1875-9572(09)60009-7","article-title":"Spontaneous multiseptated cystic pneumomediastinum in a term newborn","volume":"49","author":"Lee","year":"2008","journal-title":"Pediatr.
