A large amount of blood was aspirated through a nasogastric tube, and chest computed tomography showed bilateral centrilobular opacified lesions, which suggested aspiration pneumonitis due to upper gastrointestinal bleeding. Her respiratory condition exacerbated, and we initiated nitric oxide (NO) therapy. Bleeding stopped with conservative treatment. She was weaned off mechanical ventilation and extubated on Day 6 after admission. Afterward, upper gastrointestinal endoscopy showed a longitudinal linear scar indicative of Mallory\u2013Weiss syndrome (MWS). MWS is rarely reported in early infancy since many of the risk factors are absent in infants. Patients with aspiration pneumonitis usually recover respiratory function within 24\u00a0h and severe respiratory failure is rare in aspiration pneumonitis. There are no pediatric case reports describing MWS with severe aspiration pneumonitis. Although MWS is a rare cause of neonatal hematemesis, patients can become severely ill and require multidisciplinary treatment.<\/jats:p>","DOI":"10.1093\/omcr\/omab094","type":"journal-article","created":{"date-parts":[[2021,10,31]],"date-time":"2021-10-31T12:35:01Z","timestamp":1635683701000},"source":"Crossref","is-referenced-by-count":0,"title":["Mallory\u2013Weiss
