Paraovarian cystadenoma is a usually benign adnexal tumor that does not arise from the ovary. There is an association with Von Hippel Lindau syndrome.
Radiographic features
Pelvic ultrasound
- typically seen as a unilateral cystic adnexal lesion
- may be a simple cyst, or contain solid nodular areas within it
- the majority have septations or a thick and/or irregular wall
The relationship to the ovary can sometimes be difficult to determine on ultrasound.
Differential diagnosis
