Background To evaluate the preoperative clinical, laboratory and sonographic characteristics of struma ovarii. Method A retrospective review of gynecologic patients operated for mature cystic teratoma over a 10‐year period, identified 16 cases of struma ovarii. These cases were the subject of this study and were compared to 32 cases of ovarian dermoid cysts. Results The incidence of struma ovarii among all cases of dermoid cysts was 4.8%. Most patients were menopausal, the mean lesion diameter was 57.3 mm, occurred more frequently (68.8%) in the right adnexa and presented with normal CA‐125 level. Blood flow signals were detected from the center of the lesions in all cases. Rare cases presented with elevated tumor marker and low‐resistance blood flow. In dermoid cycsts, blood flow had a higher resistive index. In addition, no blood flow could be detected from the center of the echogenic lesion in dermoid ( P < 0.0001). Conclusion It is difficult to distinguish between struma ovarii and dermoid cysts, based on their sonographic appearance. Nevertheless, Doppler flow may aid in the preoperative diagnosis of struma ovarii. Blood flow signals, detected from the center of the echogenic lesions and low resistance to flow may be more common in struma ovarii.
