Sonographic features of ovarian cystadenofibromas: spectrum of findings.

OBJECTIVE: To describe the sonographic characteristics of ovarian cystadenofibromas.

METHODS: We conducted a retrospective study of 23 ovarian tumors histopathologically confirmed as ovarian cystadenofibromas that were preoperatively evaluated by transvaginal color Doppler sonography.

RESULTS: In all cases the mass was predominantly cystic. Septations appeared in 30.4% of the tumors. Papillary projections or solid nodules appeared in 56.5% of the cases. The most frequent appearance was a unilocular complex cystic mass. In 47.8% of the tumors, vascularization was detected, having a typical pattern of peripheral vascularization with scattered vessels of high blood flow impedance.

CONCLUSIONS: We have described the sonographic spectrum of findings of ovarian cystadenofibromas. The most frequent appearance was a unilocular cystic mass with gross papillary projections or solid nodules. In almost half of the tumors, vascularization could be detected.
