Abstract
OBJECTIVES
To characterize the ultrasonographic findings of struma ovarii, a rare ovarian tumor composed solely or predominantly of thyroid tissue or the tumor in which hyperthyroidism results from the ovarian thyroid tissue.
MATERIALS AND METHODS
Using ultrasonography, preoperative ultrasonographic findings of pathologically proven struma ovarii in six patients were retrospectively evaluated for the site, size, margin, nature (cystic, solid, mixed), septa, mural nodule, calcification, fat, and metastasis. The findings were compared with pathologic findings.
RESULTS
All six were unilateral, and smooth tumor margins, 5 were mixed cystic and solid tumors, regular septa and scattered echogenic spots within cyst. One of our cystic tumor (bilocular) had hyperechoic mural nodules. Calcification was found in one tumor and no fat. Malignant change or metastasis was not any tumor.
CONCLUSION
Most cases of struma ovarii occurred unilaterally within ovarian teratomas in premeno- pausal women, Struma ovarii has a characteristic ultrasonographic appearance of a complex mass of multiple cysts and solid components with scattered echogenic spots within cyst.
