Most paediatric liver tumours in this age group are malignant, making an accurate diagnosis essential. We report a case of FNH involving the left hepatic lobe in a healthy child with no prior history of liver disease, chemotherapy or systemic illness. The child presented with a gradually enlarging abdominal mass and early satiety. Imaging with contrast-enhanced triple-phase CT demonstrated classical features of FNH, including arterial enhancement and a central scar. Due to the lesion\u2019s large size and associated symptoms, a left lateral segmentectomy was performed. Histopathology confirmed the diagnosis of FNH. Postoperative recovery was uneventful, and the patient remains well on long-term follow-up. This case highlights the diagnostic challenges of FNH in early childhood and the importance of considering benign hepatic lesions in the differential diagnosis of paediatric liver masses.<\/jats:p>","DOI":"10.1136\/bcr-2025-270129","type":"journal-article","created":{"date-parts":[[2026,9,1]],"date-time":"2026-09-01T11:10:14Z","timestamp":1788261014000},"page":"e270129","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Focal nodular hyperplasia: a rare benign liver tumour in early childhood without predisposing factors"],"prefix":"10.1136","volume":"19","author":[{"given":"Nishant","family":"Agarwal","sequence":"first","affiliation":[{"name":"Pediatric Surgery, Sanjay Gandhi Post Graduate Institute of Medical Sciences, Lucknow, Uttar Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tarun","family":"Kumar","sequence":"additional","affiliation":[{"name":"Pediatric Surgery, Sanjay Gandhi Post Graduate Institute of Medical Sciences, Lucknow, Uttar Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Priya","family":"Mathew","sequence":"additional","affiliation":[{"name":"Pediatric Surgery, Sanjay Gandhi Post Graduate Institute of Medical Sciences, Lucknow, Uttar Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Basant","family":"Kumar","sequence":"additional","affiliation":[{"name":"Pediatric Surgery, Sanjay Gandhi Post Graduate Institute of Medical Sciences, Lucknow, Uttar Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2026,9,1]]},"reference":[{"key":"2026090104100732000_19.9.e270129.1","first-page":"97","article-title":"Pedunculated focal nodular hyperplasia in a healthy toddler","volume":"31","author":"Koolwal","year":"2018","journal-title":"Proc (Bayl Univ Med Cent)"},{"key":"2026090104100732000_19.9.e270129.2","doi-asserted-by":"crossref","first-page":"1266","DOI":"10.1007\/s00247-014-2975-3","article-title":"Gadobenate-dimeglumine-enhanced magnetic resonance imaging for hepatic lesions in children","volume":"44","author":"Chavhan","year":"2014","journal-title":"Pediatr Radiol"},{"key":"2026090104100732000_19.9.e270129.3","doi-asserted-by":"crossref","first-page":"382","DOI":"10.1016\/j.jpedsurg.2014.06.016","article-title":"Focal nodular hyperplasia in children: an institutional experience with review of the literature","volume":"50","author":"Ma","year":"2015","journal-title":"J Pediatr Surg"},{"key":"2026090104100732000_19.9.e270129.4","doi-asserted-by":"crossref","DOI":"10.1186\/s12876-017-0719-1","article-title":"Efficacy comparison of multi-phase CT and hepatotropic contrast-enhanced MRI in the differential diagnosis of focal nodular hyperplasia: a prospective cohort study","volume":"18","author":"Nowicki","year":"2018","journal-title":"BMC Gastroenterol"},{"key":"2026090104100732000_19.9.e270129.5","first-page":"52","article-title":"Focal nodular hyperplasia of the liver in 86 patients","volume":"6","author":"Shen","year":"2007","journal-title":"Hepatobiliary Pancreat Dis Int"},{"key":"2026090104100732000_19.9.e270129.6","first-page":"5","article-title":"Focal nodular hyperplasia of the liver","volume":"4","author":"Geller","year":"2014","journal-title":"Autops Case Rep"},{"key":"2026090104100732000_19.9.e270129.7","doi-asserted-by":"crossref","first-page":"611","DOI":"10.1016\/S1726-4901(10)70133-7","article-title":"Focal nodular hyperplasia of the liver in a 5-year-old girl","volume":"73","author":"Chen","year":"2010","journal-title":"J Chin Med Assoc"},{"key":"2026090104100732000_19.9.e270129.8","doi-asserted-by":"crossref","first-page":"76","DOI":"10.1016\/j.ijscr.2016.10.053","article-title":"Huge focal nodular hyperplasia presenting in a 6-year-old child: A case presentation","volume":"29","author":"Zhuang","year":"2016","journal-title":"Int J Surg Case Rep"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2025-270129","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,9,1]],"date-time":"2026-09-01T11:10:15Z","timestamp":1788261015000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2025-270129"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,9]]},"references-count":8,"journal-issue":{"issue":"9","published-online":{"date-parts":[[2026,9,1]]},"published-print":{"date-parts":[[2026,9]]}},"alternative-id":["10.1136\/bcr-2025-270129"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2025-270129","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,9]]}}}
