Objective. To describe the sonographic characteristics of ovarian cystadeno
fibromas. Methods. We conducted a retrospective study of 23 ovarian tumors
histopathologically confirmed as ovarian cystadenofibromas that were preope
ratively evaluated by transvaginal color Doppler sonography. Results. In al
l 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 patt
ern of peripheral vascularization with scattered vessels of high blood flow
impedance. Conclusions. We have described the sonographic spectrum of find
ings of ovarian cystadenofibromas. The most frequent appearance was a unilo
cular cystic mass with gross papillary projections or solid nodules. In alm
ost half of the tumors, vascularization could be detected.
