Paraovarian cystadenomas and cystadenofibromas: sonographic characteristics in 14 cases.
OBJECTIVE
To describe the sonographic features of paraovarian cystadenomas.


METHODS
We searched the computerized pathology and radiology databases for cases of histopathologically proved paraovarian cystadenomas from January 1993 through December 1996 in which preoperative sonography had also been performed. Fourteen paraovarian cystadenomas or cystadenofibromas were identified in 14 patients aged 20-57 years. Sonographic and pathologic findings were correlated.


RESULTS
Three of the masses appeared as simple cysts sonographically. Of the remaining 11 masses, nine had solid nodular areas within the cyst; three had septations; and four had a thick wall, an irregular wall, or both at sonography. At sonography, four masses were thought to arise outside the ovary, four were erroneously thought to arise in the ovary, and the location was uncertain in six.


CONCLUSIONS
Paraovarian cystadenomas are cystic masses that usually contain one or more small solid nodules and occasionally contain septations.
