Paratubal (Paraovarian) Cyst

Clinical Notes

Pathology – Giant right paratubal cyst; hemorrhagic right corpus luteum cyst.


CT – Large fluid attenuation lesion pelvic mass extending into the abdomen. Note the right larger than left ovarian cysts.


Paraovarian cysts account for 10%–20% of all adnexal masses. They arise from the mesosalpinx (the superior, free border of the broad ligament)which invests the fallopian tube. Paraovarian cysts occur over a wide age range, but they are most common in women in the 3rd and 4th decades of life. Paraovarian cysts vary in size although the average size at diagnosis is 8 cm. Bilateral cysts and multiple unilateral cysts have been documented. US, CT and MR typically depict a simple unilocular round or oval cyst separate from the ipsilateral ovary. Rarely, it may be complicated by torsion or hemorrhage. The presence of soft tissue within the cyst may indicate a benign or malignant neoplasm (cystadenoma or cystadenocarcinoma), a rare complication.
