CT and MRI findings of sex cord-stromal tumor of the ovary

OBJECTIVE. The purpose of this article was to research the clinical and imaging features of sex cord-stromal tumors of the ovary to help in specific diagnosis of ovarian tumors. Sex cord-stromal tumors of the ovary are rare ovarian neoplasms, which arise from stromal cells and primitive sex cords in the ovary. The common types are granulosa cell tumors, fibrothecomas, sclerosing stromal tumors, and Sertoli-Leydig cell tumors. They account for most of the hormonally active ovarian tumors. They have characteristic imaging features in each type of the tumor. CONCLUSION. Clinical and radiologic clues are helpful in differential diagnosis from the more common epithelial tumors; sex cord-stromal tumors primarily are treated surgically and have generally good prognosis.
