Clinical, radiological, and histopathological analysis of paraovarian cysts

INTRODUCTION: Paraovarian cyst arise from either mesothelium or from paramesonephric remnant. These present as either adneal mass or as an incidental finding. Diagnosis is usually established on ultrasound and it is important to differentiate these from ovarian cyst. MATERIAL AND METHODS: The present study is a retrospective analysis of 32 women with a confirmed diagnosis of paraovarian cyst after surgery. The clinical profile, symptoms and radiological findings of these patients were noted from the hospital records. A correlation was made with the surgical findings and the final histopathological diagnosis. RESULTS: Only 2 patients were postmenopausal and one case was diagnosed during pregnancy. Ultrasound accurately diagnosed paraovarian cyst in 87.5% patients. 78% paraovarian cysts were found to be simple and none had any malignant change. We reported a higher incidence of cystic adenomatoid tumor in these paraovarian cysts. CONCLUSION: In our study, most paraovarian cysts occur in reproductive age group and present as an adnexal mass. Ultrasound is the diagnostic modality and a paraovarian cyst needs to be differentiated from ovarian cyst. Most of them were simple cysts on histopathology.
