A case of torsioned giant mucinous cystadenoma mimicking mesenteric cyst
Abstract
Ovarian mucinous cystadenomas are cystic neoplasms lined by mucin-producing epithelial cells. They account for ~15%–20% of ovarian tumors, and in 80% of the cases, they are benign. Intra-abdominal mucinous cystic neoplasms commonly arise from the ovaries but can rarely arise from the mesentery. Here, we report a case of a 49-year-old para II mother who presented with a complaint of progressive abdominal swelling and discomfort of 6 months duration. She had an ill-defined mass around the peri-umbilical and lower abdominal area. Abdominopelvic ultrasound suggested a mesenteric cyst, while computed tomography showed a large, thick-walled cystic lesion of ovarian origin. Determining the tissue of origin of a giant cyst that involves both the mesentery and adnexa is difficult. Torsion of a massive ovarian cyst is a rare gynecologic emergency that involves both diagnostic and management challenges. No matter the diagnostic dilemmas, surgery is the mainstay of treatment.
