Paraovarian/paratubal cysts: comparison of transvaginal sonographic and pathological findings to establish diagnostic criteria

Abstract

Objectives To describe the sonographic features of paraovarian cysts and to compare these features with pathological findings in order to define the best treatment options (surgical vs. conservative).Methods Fifty patients (mean age 48 (range, 14-68) years), each with a surgically proven paraovarian cyst, were retrospectively recruited. Preoperative transvaginal ultrasonographic B-mode and power Doppler observations were re-evaluated and histological reports were analyzed. Results All cysts were correctly diagnosed as paraovarian at preoperative transvaginal sonography (TVS). Paraovarian cysts appeared as unilocular ('simple') cysts in 33 (66%) cases and multilocular in two (4%). In 15 patients (30%) the cyst showed a variable number of papillary projections growing from the cyst wall (unilocular-solid cysts). Power Doppler examination of the papillae showed the presence of blood vessels in four of these patients (27%

A study of benign adnexal masses

“…11 Except mucinous cystadenoma which was multiseptate almost all adnexal tumors were reported as unilocular anechoic cyst. 12,13 In our study, the cysts ranged from 5 cm to 36 cm, mostly unilocular and echo-free in the postmenopausal women and were reported as either functional cysts or benign tumors. Ekerhovd et al reported that the risk of malignancy associated with unilocular echo-free cysts was not higher than 1.6%.…”

Clinical diagnosis and complications of paratubal cysts: review of the literature and report of uncommon presentations

“…The differential diagnosis of paratubal and paraovarian cyst by ultrasonography requires greater awareness and accuracy [7]. The dissocation of the cyst from the ovary when pushing the probe is a useful sign, called as ''Split sign'', for discriminating paraovarian masses [8]. Darwish et al [7], reported definite preoperative transvaginal sonography diagnosis in 44 % of the cases (52/118 patients).…”

Multi-Focal Endometriosis in a Young Woman with Adnexal Para-Mesonephric Cyst: Role of MRI in Surgical Planning

“…The persistence of residual of para-mesonephric ducts or more rarely of the mesonephric ducts causes the formation of paraovarian or paratubal cysts (5-20% of the adnexal masses) [5]. Such formations result constituted by totipotent epithelium celomatic cells.…”
