This finding prompted immediate abdominal reassessment and urgent radiography, which demonstrated pneumoperitoneum. Exploratory laparotomy revealed terminal ileal perforations with ischemic changes and fecal peritonitis. Although the examination was performed for hemodynamic purposes, careful assessment of the portal venous system disclosed a clinically important abnormality unrelated to congestion. This case highlights the importance of recognizing sonographic signs suggestive of necrotizing enterocolitis and intestinal perforation during bedside POCUS to facilitate timely diagnostic escalation.<\/jats:p>","DOI":"10.1002\/jcu.70369","type":"journal-article","created":{"date-parts":[[2026,8,6]],"date-time":"2026-08-06T04:33:46Z","timestamp":1785990826000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Incidental Detection of Portal Venous Gas During\n                    <scp>POCUS<\/scp>\n                    in a Neonate With Necrotizing Enterocolitis and Intestinal Perforation: A Case Report"],"prefix":"10.1002","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6944-0221","authenticated-orcid":false,"given":"Tiago Henrique","family":"de Souza","sequence":"first","affiliation":[{"name":"Pediatric Intensive Care Unit, Department of Pediatrics Clinics Hospital of the State University of Campinas (UNICAMP)  Campinas S\u00e3o Paulo Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elisa Caixeta Fallieri","family":"Nascimento","sequence":"additional","affiliation":[{"name":"Pediatric Intensive Care Unit, Department of Pediatrics Clinics Hospital of the State University of Campinas (UNICAMP)  Campinas S\u00e3o Paulo Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-2050-190X","authenticated-orcid":false,"given":"Fernando de Lima","family":"Carioca","sequence":"additional","affiliation":[{"name":"Pediatric Intensive Care Unit, Department of Pediatrics Clinics Hospital of the State University of Campinas (UNICAMP)  Campinas S\u00e3o Paulo Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nayara Hillebrand","family":"Franzon","sequence":"additional","affiliation":[{"name":"Pediatric Intensive Care Unit, Department of Pediatrics Clinics Hospital of the State University of Campinas (UNICAMP)  Campinas S\u00e3o Paulo Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-9671-7009","authenticated-orcid":false,"given":"Humberto Magalh\u00e3es","family":"Silva","sequence":"additional","affiliation":[{"name":"Pediatric Intensive Care Unit, Department of Pediatrics Clinics Hospital of the State University of Campinas (UNICAMP)  Campinas S\u00e3o Paulo Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,8,5]]},"reference":[{"issue":"9","key":"e_1_2_11_2_1","doi-asserted-by":"crossref","first-page":"3621","DOI":"10.1007\/s00330-018-5362-x","article-title":"The Role of Imaging in the Management of Necrotising Enterocolitis: A Multispecialist Survey and a Review of the Literature","volume":"28","author":"Ahle M.","year":"2018","journal-title":"European Radiology"},{"key":"e_1_2_11_3_1","doi-asserted-by":"crossref","first-page":"535","DOI":"10.1007\/s00383-018-4256-y","article-title":"Comparison of Abdominal Radiographs and Sonography in Prognostic Prediction of Infants With Necrotizing Enterocolitis","volume":"34","author":"Chen S.","year":"2018","journal-title":"Pediatric Surgery International"},{"key":"e_1_2_11_4_1","doi-asserted-by":"crossref","first-page":"113","DOI":"10.1097\/RUQ.0000000000000342","article-title":"Bowel Ultrasound for the Diagnosis of Necrotizing Enterocolitis: A Meta\u2010Analysis","volume":"34","author":"Cuna A.
