Brenner Tumor

Synonyms/Description

Transitional cell tumor of the ovary
Typically asymptomatic, rare, benign ovarian tumor

Etiology

These tumors account for approximately 3.2% of ovarian epithelial neoplasms and typically occur in the fourth to sixth decades of life. They belong to the combined surface epithelial-stromal group of tumors, although they have been described as having similar histologic appearance to transitional cell tumors of the urothelium.

Ultrasound Findings

These masses are typically solid, hypoechoic, frequently contain some calcifications, and have minimal detectable color Doppler flow. Approximately 25% of the time, there is a cystic component indicating the possible presence of a co-existent cystic epithelial neoplasm, such as a serous or mucinous cystadenoma. These cystic components can have solid papillations, and they may be malignant (about 15% of cases).
