Multiple Intraabdominal and Pelvic Cystadenomas From Ovarian Remnant Syndrome

Serous cystadenomas are benign epithelial neoplasms of the ovary, and they typically have an average size of around 10 cm. Our patient is a 68-year-old female who originally presented with abdominal page. Our patient’s prior surgical history includes a bilateral salpingo-oophorectomy. Computed tomography scans showed five abdominal and pelvic masses of significant size. Our patient elected to undergo exploratory laparotomy and mass excision, and all five masses were able to be removed successfully. Final pathology confirmed the diagnosis of serous cystadenomas consistent with ovarian origin despite our patient undergoing a previous bilateral salpingo-oophorectomy. Our patient presented with a rare syndrome known as ovarian remnant syndrome that is thought to be caused by difficult hysterectomy procedures and prior abdominal surgeries that can unknowingly leave ovarian remnants. Second, the patient was found to have 5 abdominal and pelvic masses, and most of the masses were a very large size.
