Appendiceal Intussusception Caused by the Mucocele of the Appendix

ABSTRACT

Mucocele of the appendix is basically a cystic dilatation of the appendix distal to an obstruction of the appendiceal lumen. It develops in unusual situations in which the distal lumen does not contain enough bacteria to initiate appendicitis when obstruction develops. The continuing mucous secretion causes gradual distention of the appendix and thinning of the wall until mucous secretion stops. The changes after the sudden blocking of the lumen of the appendix depend on the amount and character of the content distal to the obstruction. If the lumen is empty, the appendix distends with mucus to form a mucocele. Here we report a case which we experienced a 68-years-old female patient whose vermiform appendix had mucoceles with appendiceal intussusception.
