Appendiceal mucocele is cystic dilation of the veriform appendix from accumulation of mucoid substance within the lumen. It is either simple which develops after appendicitis if the lumen became obstructed by fibrosis or one associated with cystadenoma or cystadenocarcinoma.It is a rare condition encountered in only 0.1 - 0.4% of all appendicectomies. We reported a case that presented to agynaecologist with a picture simulating ovarian cyst torsion and we briefly reviewed the literature.
