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.
