Ultrasonography was performed at baseline, during follow-up, before the discharge, and at 15-day intervals until US findings of OI disappeared. All children with a diagnosis of OI were treated conservatively.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results<\/jats:title>\n            <jats:p>One hundred ninety-nine children (91 male; age range, 3\u201315 years) were evaluated. Eighty-four patients had acute appendicitis. Omental infarctions were found in 14 children (8 male; mean age, 9.8 \u00b1 2.6 years), with an incidence of 7%. Ultrasonography depicted an echogenic mass consistent with OI in all children. Ultrasonography detected in 8 patients a normal-looking appendix, whereas in other 6 patients, it identified neither appendix nor indirect signs of acute appendicitis. A normal appendix has been detected by US during follow-up in 2 of these 6 patients. During follow-up, US finding of OI disappeared in all cases and no signs of acute appendicitis or other disease occurred. All 14 OIs were treated conservatively, with no reported complications.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions<\/jats:title>\n            <jats:p>Omental infarction is an underestimated cause of abdominal pain in children accounting for 7% of patients with suspected appendicitis. Ultrasonography is a useful method for the diagnoses and to guide clinical management of OI. Conservative therapy is a safe option for the management of OI.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1097\/pec.0000000000002114","type":"journal-article","created":{"date-parts":[[2020,7,13]],"date-time":"2020-07-13T06:00:09Z","timestamp":1594620009000},"page":"e1555-e1559","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":7,"title":["Omental Infarction"],"prefix":"10.1097","volume":"37","author":[{"given":"Giovanni","family":"Di Nardo","sequence":"first","affiliation":[{"name":"NESMOS Department, School of Medicine and Psychology, Sapienza University of Rome, Sant'Andrea University Hospital, Rome"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marco","family":"Di Serafino","sequence":"additional","affiliation":[{"name":"General and Emergency Radiology Unit, Antonio Cardarelli Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giovanni","family":"Gaglione","sequence":"additional","affiliation":[{"name":"Pediatric Surgery"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carmela","family":"Mercogliano","sequence":"additional","affiliation":[{"name":"Pediatric Gastroenterology Units, Santobono-Pausilipon Children Hospital, Naples"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luigi","family":"Masoni","sequence":"additional","affiliation":[{"name":"General Surgery Unit, Sapienza University of Rome, Sant'Andrea University Hospital, Rome"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria Pia","family":"Villa","sequence":"additional","affiliation":[{"name":"NESMOS Department, School of Medicine and Psychology, Sapienza University of Rome, Sant'Andrea University Hospital, Rome"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pasquale","family":"Parisi","sequence":"additional","affiliation":[{"name":"NESMOS Department, School of Medicine and Psychology, Sapienza University of Rome, Sant'Andrea University Hospital, Rome"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chiara","family":"Ziparo","sequence":"additional","affiliation":[{"name":"NESMOS Department, School of Medicine and Psychology, Sapienza University of Rome, Sant'Andrea University Hospital, Rome"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francesca","family":"Vassallo","sequence":"additional","affiliation":[{"name":"NESMOS Department, School of Medicine and Psychology, Sapienza University of Rome, Sant'Andrea University Hospital, Rome"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Melania","family":"Evangelisti","sequence":"additional","affiliation":[{"name":"NESMOS Department, School of Medicine and Psychology, Sapienza University of Rome, Sant'Andrea University Hospital, Rome"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gianfranco","family":"Vallone","sequence":"additional","affiliation":[{"name":"Paediatric Radiology Unit, Federico II University Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francesco","family":"Esposito","sequence":"additional","affiliation":[{"name":"Radiology Unit, Santobono-Pausilipon Children Hospital, Naples, Italy."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2020,7,8]]},"reference":[{"key":"bib1-20250504","doi-asserted-by":"crossref","first-page":"427","DOI":"10.1016\/j.jpeds.2009.03.039","article-title":"Omental infarction in children","volume":"155","year":"2009","journal-title":"J Pediatr"},{"key":"bib2-20250504","doi-asserted-by":"crossref","first-page":"1098","DOI":"10.1542\/peds.2012-3672","article-title":"Race and acute abdominal pain in a pediatric emergency department","volume":"131","year":"2013","journal-title":"Pediatrics"},{"key":"bib3-20250504","doi-asserted-by":"crossref","first-page":"22","DOI":"10.1111\/j.1440-1754.1996.tb01535.x","article-title":"Primary omental torsion in children","volume":"32","year":"1996","journal-title":"J Paediatr Child Health"},{"key":"bib4-20250504","doi-asserted-by":"crossref","first-page":"953","DOI":"10.1016\/j.jpedsurg.2009.01.032","article-title":"Primary omental infarct: conservative vs operative management in the era of ultrasound, computerized tomography, and laparoscopy","volume":"44","year":"2009","journal-title":"J Pediatr Surg"},{"key":"bib5-20250504","first-page":"275","article-title":"The greater omentum.
