Cystadenofibromas: Can transvaginal ultrasound appearance reduce some surgical interventions?
Journal of Clinical Ultrasound : JCU 2015 July
PURPOSE: Cystadenofibromas are benign ovarian neoplasms. Their most typical features on sonography (US) are unilocular cysts with small, shadowing hyperechoic, solid papillae without internal vascularity. In the past, they were virtually always surgically removed to exclude malignancy. This study was undertaken to review the sonographic appearances of benign cystadenomas.
METHODS: We retrospectively reviewed the transvaginal US studies of 32 cases of pathologically proven ovarian cystadenofibromas.
RESULTS: Twenty-two of the tumors presented as unilocular cystic structures with one or more solid, hyperechoic, shadowing, mural nodules with no discernible blood flow projecting from the inner cyst wall. Ten lesions were multiloculated with multiple small solid areas, with scant or no blood vessels.
CONCLUSIONS: Cystadenofibromas do not always have a classic appearance on transvaginal US and color Doppler imaging. In our series, however, the majority (69%) presented as unilocular cysts with one or more small solid, avascular projections from the inner cyst wall. These features had 100% reliability for a diagnosis of benign cystadenofibroma in this small series. Further study is necessary to confirm the reliability of this finding for benign cystadenofibroma, thus possibly avoiding or minimizing any surgical exploration.
