Mucocele of the appendix is a rare entity, not often considered when problems pertaining to the right lower abdominal quadrant are encountered. We describe the case of a patient with a large cystic mass in the lower abdomen, with extension into the pelvis. Pathological examination confirmed the diagnosis of appendiceal mucocele due to underlying cystadenoma. The condition of appendiceal mucocele is discussed and diagnostic imaging features described.
