Presentation
Abdominal bloating.
Patient Data

A large unilocular cystic lesion, located in the midline. There are no evident solid components, papillary projections or internal septations. On ultrasound, it is difficult to assess the lesion in its entirety due to the very large size. The right ovary is identified, separate to the mass. Left ovary not visualized.






CT confirms the presence of a large, solitary well-defined abdominopelvic cystic mass lesion. There are no internal septations, solid components or papillary projections.
There is a small amount of pelvic free fluid.
Case Discussion
A very large, unilocular cystic mass, with no concerning morphologic features to suggest a high-grade malignancy. As they are asymptomatic apart from the mass effect, it is not uncommon for benign ovarian neoplasms to be very large at presentation.
Shown to be an ovarian serous cystadenoma.
