Mucocele represents mucinous dilation of the lumen of vermiform appendix resulting from obstruction or increase secretion. It is a rare disease with an incidence of 0.2–0.7% of all appendectomies and 8–10% of all appendiceal tumours. The clinical presentation is atypical with most cases usually asymptomatic. Mucocele of the appendix indicates dilation of the appendix lumen irrespective of the aetiology. Four types of appendiceal mucocele are defined by the cause of obstruction: retention cysts, epithelial hyperplasia, mucinous cystadenoma and mucinous cystadenocarcinoma. Mucocele of the appendix is a rare condition of the appendix that requires high index of suspicion for a definitive preoperative diagnosis. The treatment for appendiceal mucocele is typically surgical resection. We report a case of a 37-year-old woman with recurrent right iliac fossa pain of 20 years duration. Abdomen was full, moved with respiration with a positive pointing sign. There was marked right iliac fossa tenderness with rebound tenderness and guarding. She had an abdominopelvic ultrasonography that revealed features of acute appendicitis. She had surgery with intraoperative finding of marked distension of the appendix from the tip to the base with necrosis at the base, a right hemicolectomy was done.
