Mycoplasma pneumonia-associated DAH is rare.<\/jats:p><\/jats:sec><jats:sec><jats:title>Case Presentation<\/jats:title><jats:p>We report a case of severe pediatric mycoplasma pneumonia in an immuno-competent child. This patient's condition progressed rapidly, with severe lung lesions associated with pleural effusion, coagulopathy, diffuse alveolar haemorrhage and severe respiratory distress requiring ventilator and intravenous extracorporeal membrane oxygenation (VV-ECMO) support.

Early detection and diagnosis are very important. The main treatment measures include anti-infection and supportive measures such as mechanical ventilation, but as in our case, success with both prone positioning for more than 10\u2005h per day and VV-ECMO was life-saving.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fped.2022.925655","type":"journal-article","created":{"date-parts":[[2023,1,6]],"date-time":"2023-01-06T14:07:01Z","timestamp":1673014021000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":8,"title":["Severe
