CT and MRI Findings of Brenner Tumor of Ovary:A Report of 14 Cases
Objective To investigate the CT and MRI features of Brenner tumor of ovary in order to improve the understanding and diagnosis of the disease.Methods The clinical and imaging features of 14 cases of ovarian Brenner tumor confirmed by surgical pathology in our hospital from October 2019 to March 2023 were retrospectively analyzed.Results All the 14 patients with Brenner's tumor were postmenopausal and were unilateral,with 10 patients on the left side and 4 patients on the right side.12 cases were benign,1 case borderline and 1 case malignant.There were 7 cases of solid-cystic,4 cases of solid and 3 cases of cystic.Solid part T2WI showed low signal or mainly low signal,mixed with high signal.The ADC values of the solid part ranged from 0.25 to 1.17×10-3mm2/s,with an average ADC value of 1.14×10-3mm2/s,including 1 malignant patient with an ADC value of 1.01×10-3mm2/s,and 4 benign patients with an ADC value below 1.0×10-3mm2/s.There were 9 cases with calcification,of which 1 case was borderline and 1 case was malignant.7 cases showed mild to moderate progressive enhancement,and 3 cases(1 of which was malignant)had continuous upward TIC curve.4 cases combined with mucious cystadenoma.Conclusion Brenner tumor of ovary has certain imaging characteristics.often accompanied by calcification,a wide range of ADC values,and a continuously rising TIC curve.However,calcification,ADC value,and TIC curve type cannot be used as the basis for judging benign and malignant.
