Among these manifestations, hepatic injury and acute pancreatitis are rarely reported in pediatric patients. We describe the case of an 11-year-old boy who developed recurrent fever and abdominal pain after initial improvement from M. pneumoniae pneumonia. On admission, he exhibited markedly elevated aspartate aminotransferase and alanine aminotransferase levels, along with significant increases in amylase and lipase. Abdominal ultrasonography demonstrated mild pancreatic swelling and thickening of the gallbladder and common bile duct walls, consistent with acute pancreatitis and associated hepatobiliary inflammation. The patient was treated with nil per os, intravenous hydration, analgesics, proton pump inhibitors, and continued azithromycin therapy. His abdominal pain gradually improved, and liver and pancreatic enzyme levels normalized over the course of hospitalization. He was discharged after 6 days, and follow-up ultrasonography confirmed complete resolution of pancreatobiliary abnormalities. This case underscores the importance of considering acute pancreatitis when abdominal pain and elevated liver enzymes develop during the course of M. pneumoniae infection, even in patients with improving respiratory symptoms. Early recognition and supportive management can help prevent complications and ensure favorable outcomes.\n                  <\/jats:p>","DOI":"10.3389\/fped.2026.1750118","type":"journal-article","created":{"date-parts":[[2026,4,2]],"date-time":"2026-04-02T05:25:47Z","timestamp":1775107547000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Acute pancreatitis and hepatitis in an 11-year-old boy following Mycoplasma pneumoniae infection: case report"],"prefix":"10.3389","volume":"14","author":[{"given":"Ji-Hyuk","family":"Lee","sequence":"first","affiliation":[{"name":"Department of Pediatrics, College of Medicine, Chungbuk National University","place":["Cheongju, Republic of Korea"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2026,4,2]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"23","DOI":"10.3389\/FMICB.2016.00023","article-title":"Classification of extrapulmonary manifestations due to mycoplasma pneumoniae infection on the basis of possible pathogenesis","volume":"7","author":"Narita","year":"2016","journal-title":"Front Microbiol"},{"key":"B2","doi-asserted-by":"publisher","first-page":"380","DOI":"10.1097\/BOR.0000000000000494","article-title":"Extra-pulmonary diseases related to mycoplasma pneumoniae in children: recent insights into the pathogenesis","volume":"30","author":"Poddighe","year":"2018","journal-title":"Curr Opin Rheumatol"},{"key":"B3","doi-asserted-by":"publisher","first-page":"561","DOI":"10.3389\/fpsyg.2016.00561","article-title":"The flexibility of conceptual pacts: referring expressions dynamically shift to accommodate new conceptualizations","volume":"7","author":"Ibarra","year":"2016","journal-title":"Front Psychol"},{"key":"B4","doi-asserted-by":"publisher","first-page":"e25052","DOI":"10.7759\/cureus.25052","article-title":"Acute pancreatitis: an unusual extrapulmonary manifestation of mycoplasma pneumoniae","volume":"14","author":"Khan","year":"2022","journal-title":"Cureus"},{"key":"B5","doi-asserted-by":"publisher","first-page":"279","DOI":"10.1007\/s12328-017-0733-4","article-title":"Acute pancreatitis caused by mycoplasma pneumoniae: an unusual etiology","volume":"10","author":"Vald\u00e9s Lacasa","year":"2017","journal-title":"Clin J Gastroenterol"},{"key":"B6","doi-asserted-by":"publisher","first-page":"211","DOI":"10.3345\/kjp.2015.58.6.211","article-title":"Hepatitis associated with mycoplasma pneumoniae infection in Korean children: a prospective study","volume":"58","author":"Kim","year":"2015","journal-title":"Korean J Pediatr"},{"key":"B7","doi-asserted-by":"publisher","first-page":"124","DOI":"10.5223\/pghn.2017.20.2.124","article-title":"Pediatric mycoplasma pneumoniae infection presenting with acute cholestatic hepatitis and other extrapulmonary manifestations in the absence of pneumonia","volume":"20","author":"Song","year":"2017","journal-title":"Pediatr Gastroenterol Hepatol Nutr"},{"key":"B8","doi-asserted-by":"publisher","first-page":"1416189","DOI":"10.3389\/fped.2024.1416189","article-title":"Case report: mycoplasma pneumoniae\u2013associated acute pancreatitis","volume":"12","author":"Sun","year":"2024","journal-title":"Front Pediatr"},{"key":"B9","first-page":"106","article-title":"Mycoplasma pneumoniae pneumonia complicated with acute pancreatitis and hepatitis: a case study","volume":"67","author":"Hopp","year":"2013","journal-title":"Gen"},{"key":"B10","doi-asserted-by":"publisher","first-page":"397","DOI":"10.1186\/s13104-016-2196-y","article-title":"Acute pancreatitis and pneumonia due to Mycoplasma pneumoniae: a case report","volume":"9","author":"Benzaquen","year":"2016","journal-title":"BMC Res Notes"},{"key":"B11","doi-asserted-by":"publisher","first-page":"50","DOI":"10.4166\/kjg.2017.70.1.50","article-title":"Mycoplasma pneumoniae-associated hepatitis without lung involvement","volume":"70","author":"Jeong","year":"2017","journal-title":"Korean J Gastroenterol"}],"container-title":["Frontiers in Pediatrics"],"original-title":[],"link":[{"URL":"https:\/\/www.frontiersin.org\/articles\/10.3389\/fped.2026.1750118\/full","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,2]],"date-time":"2026-04-02T05:25:47Z","timestamp":1775107547000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.frontiersin.org\/articles\/10.3389\/fped.2026.1750118\/full"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,4,2]]},"references-count":11,"alternative-id":["10.3389\/fped.2026.1750118"],"URL":"https:\/\/doi.org\/10.3389\/fped.2026.1750118","relation":{},"ISSN":["2296-2360"],"issn-type":[{"value":"2296-2360","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,4,2]]},"article-number":"1750118"}}
