Although it is usually benign and self-limiting, it can cause acute chest pain in children. We present a 12-year-old female patient with exercise-related spontaneous pneumomediastinum whose symptoms began 3\u2009hours after taking a ballet class focused primarily on stretching and posture. Physical examination was normal, vital signs were stable, and there was no subcutaneous crepitus. The patient was treated with analgesics and rest on an outpatient basis; complete radiographic resolution was achieved within 1\u2009week, and symptoms completely regressed. This case report highlights that activities such as ballet can be a rare trigger for SPM, the diagnostic value of lateral radiography, and the safety of conservative management in clinically stable pediatric patients.<\/jats:p>","DOI":"10.1177\/11795565261447109","type":"journal-article","created":{"date-parts":[[2026,4,30]],"date-time":"2026-04-30T12:47:56Z","timestamp":1777553276000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Exercise-Related Spontaneous Pneumomediastinum Following Ballet in a Pediatric Patient: A Case Report"],"prefix":"10.1177","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5959-6855","authenticated-orcid":false,"given":"Aykut","family":"Yucal","sequence":"first","affiliation":[{"name":"Department of Emergency Medicine, Harakani State Hospital, Kars, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-9184-3080","authenticated-orcid":false,"given":"Ferhat","family":"Demir","sequence":"additional","affiliation":[{"name":"Department of Emergency Medicine, Harakani State Hospital, Kars, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8000-361X","authenticated-orcid":false,"given":"Melike","family":"Yucal","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Harakani State Hospital, Kars, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-3167-8866","authenticated-orcid":false,"given":"Asr\u0131n Meri\u00e7","family":"Demir","sequence":"additional","affiliation":[{"name":"Department of Emergency Medicine, Harakani State Hospital, Kars, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2026,4,30]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1097\/PEC.0000000000000625"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.athoracsur.2008.04.067"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.4329\/wjr.v6.i11.850"},{"issue":"11","key":"e_1_3_3_5_2","first-page":"849","article-title":"[Diagnosis and prognosis of spontaneous pneumomediastinum in eighteen children]","volume":"51","author":"Zhang XY","year":"2013","unstructured":"Zhang XY, Zhang WX, Sheng AQ, Zhang HL, Li CC.
