Risk of perforation\/bleeding is high and a relevant association with mucinous neoplasms is known. Appendectomy is indicated even in case of occasional finding. We present the case of a 22-year-old man who entered the Emergency Room for pain in right iliac fossa. Blood tests showed only a slight increase in C-reactive protein. Abdominal ultrasound (US) evidenced an appendix with thickened walls and a rounded fluid-filled hypoechoic lesion at its distal tip. Laparoscopic appendectomy confirmed the presence of mucocele. Postoperative course was uneventful and the patients discharged on postoperative day 3. Histological examination indicated diverticulitis\/peridiverticulitis of the appendix and acute suppurative appendicitis. No perforation of the diverticula was detected. No neoplastic epithelium\/mucous material was observed. In our case, preoperative US proved to be a useful alternative to computed tomography for the diagnosis.<\/jats:p>","DOI":"10.1093\/jscr\/rjac319","type":"journal-article","created":{"date-parts":[[2022,7,4]],"date-time":"2022-07-04T18:56:37Z","timestamp":1656960997000},"source":"Crossref","is-referenced-by-count":6,"title":["Surgical rarities: case report of appendicular diverticulitis and literature review"],"prefix":"10.1093","volume":"2022","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9132-7134","authenticated-orcid":false,"given":"Luca Domenico","family":"Bonomo","sequence":"first","affiliation":[{"name":"General Surgery Unit, S.S.
