Abstract:
Appendiceal diverticulosis is a rare condition with a frequency of 0.004% to 2.1%, and is sometimes an occasional finding during anatomopathologic study of the surgical specimen. It may be presented acutely as a right lower quadrant pain, similar to acute appendicitis for which differential diagnosis must be carried out, and it is associated with appendicular tumors. We report a case of diverticulitis of the appendix as debut of appendicular cystadenoma and carcinoid tumor with representative iconography, being unusual the association of both diseases and even more its preoperative diagnosis.
