To improve the identification and computed tomography (CT) diagnostic accuracy of chronic active Epstein\u2010Barr virus (EBV)\u2010associated enteritis (CAEAE) by evaluating its CT findings and clinical manifestation. <jats:italic>Methods.<\/jats:italic> The data of three patients with pathologically and clinically confirmed CAEAE who underwent CT enterography (CTE) were retrospectively reviewed from January 2018 to October 2019. The following data were evaluated: imaging characteristics (length of involvement, pattern of mural thickening, pattern of attenuation, perienteric abnormalities), clinical symptoms, endoscopic records, laboratory examinations, and pathologic findings. <jats:italic>Results.<\/jats:italic> Based on CT findings, two patients demonstrated segmental bowel wall thickening (involvement length &gt;6\u2009cm), asymmetric thickening, layered attenuation, fat stranding, and adenopathy, whereas the remaining one had no positive finding. The endoscopic results of all patients showed numerous irregular ulcers in the colon, and one patient had a focal esophageal ulcer. The major clinical symptoms were abdominal pain (<jats:italic>n<\/jats:italic> = 3), retrosternal pain (<jats:italic>n<\/jats:italic> = 1), fever (<jats:italic>n<\/jats:italic> = 3), diarrhea (<jats:italic>n<\/jats:italic> = 2), hematochezia (<jats:italic>n<\/jats:italic> = 1), and adenopathy (<jats:italic>n<\/jats:italic> = 3). The main laboratory examination indicators were increased serum EBV DNA load (<jats:italic>n<\/jats:italic> = 1) and increased inflammatory markers (<jats:italic>n<\/jats:italic> = 3). With regard to the main pathologic findings, all patients showed positive EBV\u2010encoded RNA (EBER) situ hybridization in the colonic biopsy specimen, with one patient being positive in the esophagus. <jats:italic>Conclusion.<\/jats:italic> CAEAE is rare and is usually misdiagnosed as inflammatory bowel disease (IBD). The imaging features of CAEAE overlap with those of Crohn\u2019s disease and ulcerative colitis. The presence of segmental and asymmetric bowel wall thickening, layered attenuation, and fat stranding in the CTE image may be helpful in differentiating CAEAE from IBD.<\/jats:p>","DOI":"10.1155\/2020\/2978410","type":"journal-article","created":{"date-parts":[[2020,6,22]],"date-time":"2020-06-22T23:34:28Z","timestamp":1592868868000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Chronic Active Epstein\u2010Barr Virus\u2010Associated Enteritis: CT Findings and Clinical Manifestation"],"prefix":"10.1155","volume":"2020","author":[{"given":"Bo","family":"Zhang","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xia","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaoyan","family":"Tian","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yongping","family":"Cai","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9481-9425","authenticated-orcid":false,"given":"Xingwang","family":"Wu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2020,6,22]]},"reference":[{"volume-title":"WHO Classification of Tumours of Haematopoietic and Lymphoid Tissues","year":"2017","author":"Swerdlow S.
