Sclerosing stromal tumor of the ovary: color Doppler findings.

The sclerosing stromal tumor (SST) of the ovary is a distinct benign neoplasm that differs from fibromas, thecomas, luteinized tumors and lipoid cell tumors. It accounts for 6% of ovarian stromal tumors and tends to occur at an earlier age. On gray-scale ultrasound examination, SSTs of the ovary are solid or cystic and multilocular. We describe here, we believe for the first time, the findings on color Doppler imaging of an SST of the ovary. A 29-year-old woman presented with an organic ovarian mass. She underwent a transvaginal ultrasound examination that revealed an echogenic cyst with acoustic shadowing. Color Doppler demonstrated marked peripheral vascularization. Findings on computed tomography and magnetic resonance imaging strongly suggested the preoperative diagnosis of SST of the ovary, which was confirmed at pathology. Association of an echogenic ovarian mass with acoustic shadowing and a high degree of peripheral vascularization may strongly suggest the diagnosis of SST of the ovary. Copyright 2003 ISUOG.
