Abstract:

There is an up to 30% association between Brenner tumours and serous and mucinous cystadenomas.(1) The preoperative differentiation between benign and malignant tumours of the ovary is often difficult, especially when the tumour has both solid and cystic components.(2) We present the case of a 71-year-old woman with mucinous cystadenoma and Brenner tumour, in which ultrasound and CT examinations raised the problem of differentiating between a benign or malignant tumour. The preoperative CA 125 test was within normal range. Intraoperatively, a cystic tumoral mass was evidenced on the left ovary. The diagnosis was established by extemporaneous and histopathological examination
