Abstract
Objective: To study the CT and MRI findings of ovarian cystadenofibromas． Methods: Thirty-five patients with cystadenofibroma(36 tumors) enrolled into this study. All were confirmed by pathology. In the 35 cases, 33(91.7%) were benign serous cystadenofibroma, 1 was benign mucinous cystadenofibroma(2.7%). Twenty-two cases underwent plain CT scan, among them 18 cases also received contrast-enhanced CT. Thirteen cases underwent plain MR scan, 12 of them received contrast-enhanced MR scan. Results: On CT and MR images, tumors were mainly soild in 2 cases, with mixed components in 6 cases, multilocular cyst in 12 cases, uniocular cyst in 16 cases. After enhancement, the solid components enhanced mildly and the solid component of multilocular cyst also enhanced mildly except two case in which the solid nodule enhanced markly. Three tumors had interior bleeding and necrosis, three tumors had cystic wall calcification, two appeared “honeycomb sign”. Conclusion: Variable amounts of fibrous stromas of ovarian cystadenofibomas made the spectrum of imaging features variable from a purely cystic tumor to a complex cystic tumor. Ovarian cystadenomas are unilocular cystic masses with diffuse or partial thickening of cystic wall and septations, or multilocular cyst with irregular wall component, or multilocular cyst with solid component. CT is helpful to judge the nature of lesions, but difficult to make a definite diagnosis, while MRI due to its excellent resolution should be the imaging modality of first choice for ovarian cystadenofibomas．
