Sonographic features of parovarian cysts.

Parovarian cysts are responsible for about 10% of all adnexal masses. They arise from the tissues of the broad ligament, predominantly from mesothelium covering the peritoneum but also from paramesonephric and mesonephric remnants. When large, they become symptomatic due to pressure effect. Clinically it is difficult to distinguish an ovarian mass from one arising in the parovarium. A series of eight surgically and pathologically proven parovarian cysts is presented. All were symptomatic and most were palpable. Sonographically they were thin-walled, smoothly marginated, unilocular cysts. Six of the eight were located superior to the fundus of the uterus. Parovarian cysts should be included in the differential diagnosis along with large physiologic ovarian cysts and unilocular ovarian cystadenoma when a mass with the above sonographic features is demonstrated.

Sonographic features of parovarian cysts and their complications.

Parovarian cysts have received virtually no attention in the sonography literature, despite a common occurrence, constituting 10%-20% of adnexal tumorlike conditions in pathologic series. The sonographic features of 11 parovarian cysts, including a number with complications, are reported. Six uncomplicated lesions had the appearance of simple cysts found in other organs. One cyst had ruptured, and one lesion was associated with ipsilateral tubal torsion. Two cysts had echogenic areas representing blood clot. One cyst had a triangular papillation representing the development of a serous cystadenofibroma in its wall. This experience differs from previous reports in that there was increased incidence of preoperative recognition of an adnexal mass clinically, lack of identification of a fallopian tube exiting from the lateral aspect of the parovarian cyst and identification of complications sonographically, and the smaller average size of lesions, both clinically and sonographically. Parovarian cysts and their complications should be included in the differential diagnosis of cystic adnexal masses.

Torsion of parovarian cyst--report of two cases.

A parovarian cyst oxiginates from the tissue of the broad ligament, predominantly from mesothelium covering the peritoneum but also from paramesonephric and mesonephric remnants. Clinically, torsion of a parovarian cyst is uncommon, and it is difficult to distinguish it from torsion of other adnexal masses, an ovarian accident, appendicitis, etc. Recently, we experienced two cases of torsion of parovarian cysts. In one case, it was associated with 32 weeks' intrauterine gestation. In this case, pelvic sonography during the first and second trimester showed no cystic lesions. In the other case, a lower abdominal pain continued about two weeks. A sonogram revealed a very small cyst like a follicle. These twisted parovarian cysts were removed at laparotomy. The clinical and pathological features of the torsion of parovarian cysts are briefly discussed and the literature is reviewed.

[Parovarian cysts].

Histologic material from 117 cases of parovarian cysts through 1979 to 1984 was reviewed. The majority of these lesions were paramesonephric (mullerian), mesonephric and mesothelial in origin. Most patients were without symptoms. On microscopic examination a basement membrane may be demonstrated beneath the mesonephric epithelium, although such a layer is usually absent in the mullerian structures. Eight specimens show stratification of the epithelial lining of the papillae, four of these are parovarian cysts of low grade malignancy. These neoplasms were associated with normal tubes and ovaries. Follow up data on four low grade malignant cases showed they were living and well.

[Parovarian cysts--not always benign].

OBJECTIVES: The purpose of this study was to determinate the frequency, clinical aspects and management of epithelial parovarian neoplasms among patients hospitalised in our department. MATERIALS AND METHODS: This work has a retrospective character. The research material composed of patients treated in our clinic in the years 1992-2001 because of adnexal mass. In clinical analysis of 13 cases with epithelial parovarian neoplasms we took account of age, symptoms, ultrasound investigations, CA 125 levels, family history, operative treatment, histopathological examinations and follow up. RESULTS: Among 1110 patients operated for of adnexal mass 19.21% constituted parovarian cysts, and 2.6% (13 cases) of them were epithelial neoplasms (11 benign cystadenomas and 2 borderline malignancy neoplasms in FIGO I). The mean age of patient was 42.1. The clinical presentation was lower abdominal pain. CA 125 had the normal range in all patients. In ultrasound investigation parovarian cysts was suspected only in 2 cases when both normal ovaries were apparent. All patients were operated and extension of surgical procedures depended firs of all on age. Two patients with borderline tumors were operated in 1998 and have lived ever since without signs of disease. CONCLUSION: Parovarian cysts are not always benign and broad ligament region may be the point of issue for neoplasms of different histopathological types.

Parovarian cyst presenting as a groin hernia. A case report.

An inguinal hernia containing a parovarian cyst is extremely rare. This phenomenon occurred in a 77-year-old woman who presented with a right groin hernia. The hernia contained a cystic mass that arose between the leaves of the broad ligament and passed with the round ligament through the deep inguinal ring. Through a midline incision the hernial content was mobilized, reduced through the inguinal ring and removed from the abdomen with both ovaries, tubes and uterus. The mass was found to be a parovarian cyst of the mesothelial type.

Unusual features of parovarian cysts. A report of two cases.

In two cases, parovarian cysts were well characterized by ultrasonography and presented with unusual clinical features. In one case the cysts were present bilaterally and associated with an arcuate uterus. In the other, histology of the cyst revealed a papillary serous cystadenoma. The lesion was also associated with an arcuate uterus.

Development and classification of parovarian cysts. An ultrastructural study.

In this study the scanning and transmission electron microscopical features of parovarian cysts were analyzed to further the determination of histogenesis, development, classification and differential diagnosis of these lesions. Paramesonephric type lesions showed ciliated and microvillous cells, sometimes in a wavy arrangement with grooves and holes, similar to the oviduct epithelium. The mesonephric type consisted of an epithelium of tightly arranged angular cells with minimally developed surface structures. Destruction of specialized surface structures was frequently seen, epithelial proliferation was uncommon.
