OBJECTIVE: Adoption of transvaginal ultrasound in usual clinical settings allowed us to find asymptomatic @entity4134 more frequently in postmenopausal @entity1 . These masses were traditionally considered as the indication of surgical excision to determine histological diagnosis. Recently, if the appearance of that is simple cyst, conservative management may be acceptable because ultrasound benign diagnosis is proved to be reasonably reliable. We investigate here the reliability of benign diagnosis by MR imaging with @entity2287 enhancement for both of simple and complex postmenopausal adnexal cystic masses. METHOD: We retrospectively examined the data of 121 postmenopausal @entity1 who underwent surgery during a 3-years-period (from January, 2000 to December 2002) for @entity4134 under diagnosis of benign adnexal cysts based on MR imaging. RESULTS: Pathological examination identified two cases of @entity5 among 121 cases diagnosed as benign by MR imaging. Among the cysts that revealed a simple pattern by MR imaging, 64/66 cases (97.0%) were benign histology and among the cysts that showed a complex pattern by MR imaging, 55/55 cases (100%) were benign histology. Among the cysts with diameter less than or equal to 10cm, 48/49 simple cysts and 32/32 complex cysts were benign histology. CONCLUSIONS: The diagnosis of benign @entity4134 in postmenopausal @entity1 by MR imaging was reliable. Conservative observation for postmenopausal @entity1 of asymptomatic and small cysts under benign diagnosis based on MR imaging with @entity2287 enhancement will be feasible even if the cysts appearances are complex, with careful follow-up program.
