Mucocele of the appendix is an aseptic dilatation secondary to obstruction. The preoperative clinical diagnosis of appendiceal mucoceles can therefore be difficult because of this lack of clinical symptomotology. Surgical excision is the treatment of choice in benign mucocele. We report a case presenting to the surgeons where initial clinical findings and investigations suggested a cyst in the right adnexa. Diagnostic laparoscopy revealed mucocele of the appendix and laparoscopic appendicectomy was done.
