BACKGROUND: Acute appendicitis is common in older patients, however, the presentation may differ from the younger population and it is often complicated by coexistent disease and delays in presentation. AIMS: This case report describes an unusual presentation of acute appendicitis in an elderly patient and also demonstrates a unique anatomical pathway of disease extension. In addition, this case report highlights the advantages of CT in preoperative evaluation and subsequent management of these protean presentations of acute appendicitis. METHODS: This report describes a case of an asymptomatic retrocaecal perforated appendicitis which presented clinically as a right lumbar abscess with surrounding cellulitis, and was further complicated by a concomitant new diagnosis of type 2 diabetes mellitus in a 66-year-old male. CONCLUSION: Elderly or immunocompromised patients presenting with cellulitis or a cutaneous abscess of the abdominal wall or lumbar region may benefit from an abdominal CT to demonstrate an intraperitoneal source of sepsis.
