There is a very large mass which is largely fills the abdomen and pelvis. It is predominantly cystic with numerous septations. No discrete nodularity or solid enhancing soft tissue component is identified. There are slight prominence of the right adnexal veins which appear to lead into the posterior aspect of the mass, indicating that it comes from the right ovary. The left ovary can be seen separate from the mass, following the relatively diminutive left adnexal vein into the left lower quadrant. There is a small amount of free fluid within the pelvis.
