CT of the abdomen unveiled the presence of chronic appendicitis, alongside constipation without evidence of distal intestinal obstruction syndrome. Endoscopic biopsies revealed small bowel eosinophilic infiltrates. Subsequently, the patient underwent an appendectomy, and a tailored regimen was established to address constipation, resulting in an initial alleviation of his symptoms. Three months later, a resurgence of symptoms occurred, coinciding with persistent intestinal eosinophilic infiltrates. A diagnosis of eosinophilic enteritis was rendered, and treatment commenced with an oral dosage of 40 mg of prednisone. Two weeks later, the patient experienced symptom resolution, corroborated by the findings of an endoscopic biopsy conducted 8\u2009weeks later. During a follow-up examination 6\u2009months later, the patient remained asymptomatic.<\/jats:p>","DOI":"10.1136\/bcr-2023-257553","type":"journal-article","created":{"date-parts":[[2023,12,16]],"date-time":"2023-12-16T11:45:38Z","timestamp":1702727138000},"page":"e257553","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Eosinophilic
