We report the case of a male patient in his 50s with acute right iliac fossa abdominal pain, diagnosed via CT scan with ADA. Urgent laparoscopic appendicectomy was performed, and the patient was discharged without further issues. This case highlights the importance of promptly identifying and managing such conditions to minimise complications and improve outcomes. Despite the overlap in symptoms between appendiceal diverticulitis and acute appendicitis, accurate diagnosis is crucial for appropriate treatment. Healthcare providers should maintain a high index of suspicion, particularly in older patients presenting with an acute appendicitis, like clinical picture to ensure timely intervention and optimal patient care.<\/jats:p>","DOI":"10.1136\/bcr-2023-259552","type":"journal-article","created":{"date-parts":[[2024,4,16]],"date-time":"2024-04-16T13:27:10Z","timestamp":1713274030000},"page":"e259552","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":3,"title":["Acute diverticulitis of the appendix"],"prefix":"10.1136","volume":"17","author":[{"given":"Ahmed","family":"Abdelrahim","sequence":"first","affiliation":[{"name":"General Surgery, Health Education England North East, Newcastle upon Tyne, UK"},{"name":"County Durham and Darlington NHS Foundation Trust, Darlington, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yusuf","family":"Yusuf","sequence":"additional","affiliation":[{"name":"County Durham and Darlington NHS Foundation Trust, Darlington, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Omer","family":"Ali","sequence":"additional","affiliation":[{"name":"General Surgery, East Lancashire Hospitals NHS Trust, Blackburn, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Haytham","family":"Abudeeb","sequence":"additional","affiliation":[{"name":"General Surgery, East Lancashire Hospitals NHS Trust, Blackburn, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2024,4,16]]},"reference":[{"key":"2025082804052703000_17.4.e259552.1","unstructured":"Kelynack TN .
