Abstract

Background: A paraovarian cyst (POC) is located between the ovary and the fallopian tube. In many cases POCs are diagnosed and managed as ovarian cysts. But since POC are a distinct entity in their clinical presentation and surgical intervention, they should be better defined. Objectives: To describe the clinical perioperative and operative characteristics of patients with POCs in order to improve pre-operative diagnosis and management. Methods: A retrospective cohort study of patients with an operative diagnosis of POC between 2007 and 2019 in a single university-affiliated tertiary care medical center was included. Demographic characteristics as well as symptoms, sonographic appearance, surgery findings, and histology results were retrieved from electronic medical records. Results: During the study period 1U patients were surgically diagnosed with POC, 57.9% were in their reproductive years and 24.6% were adolescents. Most presented with abdominal pain (77.2%). Preoperative sonographic exams accurately diagnosed POC in only 44.7% of cases, and 50.9% underwent surgery due to suspected torsion, which was surgically confirmed in 70.7% of cases. Among women with confirmed torsion, 28.9% involved the fallopian tube without involvement of the ipsilateral ovary. Histology results showed benign cysts in all cases, except two, with a pathological diagnosis of serous borderline tumor. Conclusions: POC should always be part of the differential diagnosis of women presenting with lower abdominal pain and sonographic evidence of adnexal cysts. If POC is suspected there should be a high level of suspicion for adnexal torsion and low threshold for surgical intervention, especially in adolescent, population who are prone to torsion.
