Appendix mucocele mimicking a complex ovarian cyst

Abstract

Appendiceal mucocele is a rare entity which is characterized by cystic dilatation due to abnormal accumulation of mucus in the lumen of the appendix. Patients are often diagnosed incidentally by abdominal screening or abdominal surgery for other causes. Pain in the right lower quadrant of the abdomen, which may present as acute or chronic appendicitis, is the most common symptom of appendix mucocele, when the patient is symptomatic. This study describes the case of a 26-year-old female for whom surgical intervention for a complex ovarian cyst was planned, but who instead underwent laparoscopic appendectomy because appendiceal mucocele was determined during laparoscopic exploration.

Incidental appendiceal mucinous neoplasm mimicking a left adnexal mass: A case report

“…Several US appearances specific for appendiceal mucocele might be encountered e.g. a bottle-like shaped solid appendicular mass sliding over the uterus and ovaries [ 19 , 20 ] or the highly specific “onion skin sign” (concentric echogenic layers with septa and fine echoes) [ 21 , 22 ] can help to distinguish appendiceal mucocele from an ovarian cyst. Unfortunately, such diagnostic appearances were not evident in the US we undertook.…”
