Inaccurate diagnosis with a low prevalence and nonspecific symptoms leads to delayed or improper management. Methods: This retrospective study aimed to investigate the characteristic sonographic (US) and computed tomography (CT) findings with clinical features in seventeen patients with acute ileal diverticulitis diagnosed between March 2002 and August 2017. Results: The most common symptom was abdominal pain (82.3%, 14\/17) localized to the right lower quadrant (RLQ) in 14 patients. The characteristic CT findings of acute ileal diverticulitis were ileal wall thickening (100%, 17\/17), identification of inflamed diverticulum at the mesenteric side (94.1%, 16\/17), and surrounding mesenteric fat infiltration (100%, 17\/17). The typical US findings were outpouching diverticular sac connecting to the ileum (100%, 17\/17), peridiverticular inflamed fat (100%, 17\/17), ileal wall thickening with preserved layering pattern (94.1%, 16\/17), and increased color flow to the diverticulum and surrounding inflamed fat on color Doppler imaging (100%, 17\/17). The perforation group had a significantly longer hospital stay than non-perforation group (p = 0.002). In conclusion, acute ileal diverticulitis has characteristic CT and US findings that allow radiologists to accurately diagnose the disease.<\/jats:p>","DOI":"10.3390\/diagnostics13081408","type":"journal-article","created":{"date-parts":[[2023,4,14]],"date-time":"2023-04-14T01:32:03Z","timestamp":1681435923000},"page":"1408","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Acute Ileal Diverticulitis: Computed Tomography and Ultrasound Findings"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5611-2480","authenticated-orcid":false,"given":"Lyo Min","family":"Kwon","sequence":"first","affiliation":[{"name":"Department of Radiology, Hallym University Sacred Heart Hospital, Hallym University College of Medicine, Anyang 14068, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kwanseop","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Radiology, Hallym University Sacred Heart Hospital, Hallym University College of Medicine, Anyang 14068, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7484-5896","authenticated-orcid":false,"given":"Min-Jeong","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Radiology, Hallym University Sacred Heart Hospital, Hallym University College of Medicine, Anyang 14068, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"In Jae","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Radiology, Hallym University Sacred Heart Hospital, Hallym University College of Medicine, Anyang 14068, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gab Chul","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Radiology, Kyungpook National University Medical Center, Daegu 41404, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,4,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"5557","DOI":"10.3748\/wjg.v11.i35.5557","article-title":"Analysis of clinical manifestations of symptomatic acquired jejunoileal diverticular disease","volume":"11","author":"Liu","year":"2005","journal-title":"World J.
