STEROID CELL TUMORS OF THE OVARY - CLINICAL, ULTRASONIC, AND MRI DIAGNOSIS - A CASE-REPORT

Steroid cell tumors of the ovary are rare sex-cord neoplasms which acc ount for less than 0.1% of all ovarian tumors. They have been divided into two subtypes according to their cell of origin as follows: stroma l luteoma, and Leydig cell tumors, and a third subtype with lineage un known is a steroid cell tumor, not otherwise specified (NOS). The clin ical presentation may take many forms, including pain, abdominal diste ntion and bloating, but perhaps the most interesting and noticeable pr esentations are those related to the hormonal activity and virilizing properties of the tumor. No radiological features of the steroid cell tumor; NOS have been presented in the literature. This report presents the MRI and ultrasonographic findings of a patient having steroid cel l tumor, NOS, of the right ovary with metastasis to the uterus. (C) 19 98 Elsevier Science Ireland Ltd.
