LAUSR

Ovarian steroid cell tumor is a rare type of ovarian tumor, accounting for ~0.1% of all neoplasms of the ovary. Patients suffering from this type of tumor exhibit virilization due to high testosterone levels. The present study reported a case of an elderly female patient with high testosterone serum levels, resulting in hirsutism and deepening of the voice. Magnetic resonance imaging did not reveal any solid ovarian tumor. However, gray-scale ultrasound indicated suspicious solid nodules on the right ovary. A clear outline of the tumor, characterized by ring-shaped uniform enhancement, was revealed by contrast-enhanced ultrasound (CEUS) scanning. In addition, laparoscopic resection of both fallopian tubes and ovaries confirmed the right ovarian steroid cell tumor. After the operation, the patient's symptoms were completely relieved and testosterone levels returned to normal. In the present study, a case of ovarian steroid tumor diagnosed by CEUS was reported, supporting the significant role of CEUS in the detection of adnexal tumors.
