We evaluated MR manifestations of 10 ovarian adenofibromas and cystadenofibromas (8 benign and 2 borderline lesions) with pathologic correlation. Mucinous cystadenofibromas may tend to be multilocular cystic masses with solid portion showing gblack sponge-likeh appearance (very low intense solid components containing hyperintense tiny cysts on T2-weighted images), whereas serous cystadenofibromas may tend to be unilocular cystic masses with small fibrous mural nodules or masses containing aggregated small cysts with thickened fibrous wall. Fibrous components showed low intensity on diffusion-weighted imaging due to T2 blackout, and suggestive for their benignity.
