Appendiceal diverticulosis is rarely diagnosed and presentation mimics acute appendicitis. It has a documented high malignant risk and increased complication rate and excision is recommended if suspected preoperatively. We report a case of an incidental FDG avid appendiceal lesion on PET scan which was suspected to be an appendiceal neoplasm, however histologically was appendiceal diverticulosis. This is the first case of appendiceal diverticulosis detected via PET scan and we discuss the implications of this.
