An appendiceal diverticulitis patient presenting with acute appendicitis symptoms

Appendiceal diverticulitis is a very infrequent cause of pain in the right lower quadrant of the abdominal area. To have good management, it is essential to understand its clinical evolution, whether it is symptomatic or discovered incidentally during an appendectomy or barium enema. So far, few cases of appendiceal diverticulitis in different people have been reported. It is important in this case to avoid misdiagnosis in the form of another disease, especially acute appendicitis and/or possible complications. In this report we present the case of a 45-year-old man who came to the emergency room with symptoms of acute appendicitis. CT scan showed suspicious mass-like tissue in the appendiceal region, while pathological examination showed inflammation with no malignancy. An open appendicectomy was performed in this patient and appendicular diverticulitis was established as the final diagnosis.
