paraovarian cystadenoma

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

For a cystic adnexal lesion consider:

• adnexal cyst: especially if there is no solid component 
  • ovarian cyst
  • paraovarian cyst
• true ovarian cystadenoma(s)
• abdominopelvic cystic lymphangioma: younger patients
• multicystic mesothelioma in the pelvis: extremely rare
