A case report of partial bowel obstruction as the first symptom of a sizeable adnexal mucinous cystadenoma.

Objectives: Mucinous cystadenomas are among the most common benign adnexal masses. The peak incidence of mucinous cystadenoma appears between the third and fifth decades of life, but rare cases in younger and older women have also been reported. Ovarian cystic formations are usually asymptomatic at early stages, until they grow in size and various compression symptoms appear, such as abdominal discomfort, distention, nausea, vomiting, and increased urination.
