Abstract:
Objective: To observe the ultrasonic findings of ovarian thecoma (OT), and to analyze causes of missed and misdiagnosis. Methods: Data of 17 OT patients diagnosed by pathology were retrospectively analyzed, and the shape, border, internal echo, blood signal, posterior echo and ultrasonic diagnosis of OT lesions were observed. Results: There were 18 OT lesions in 17 patients, 16 case with unilateral single lesion and 1 case with bilateral single lesions, 2 (2/18, 11.11%) lesions grew outward of ovary and 16 (16/18, 88.89%) in the ovary. Fifteen lesions were found with preoperative ultrasound and 3 were missed. Among 15 OT lesions detected with ultrasound, the shape of 8 were regular and 7 were lobed, the border of 14 lesions were clear and of 1 obscure, 12 were solid, 2 were cystic and solid and 1 was cystic,11 were homogeneous hypoecho while 4 were uneven hypoecho, when CDFI found few blood signal in 9 and no blood signal in rest 6 lesions. Liquefaction was found in 3 lesions, while 12 had no liquefaction. All 15 OT lesions had no calcification, while 2 lesions had posterior echo attenuation and 13 had no attenuation. Among these 15 lesions, preoperative ultrasound only correctly diagnosed 1 lesion as OT. In the rest 14 lesions, preoperative ultrasound could not locate and quantitate 1 lesion, while located 6 lesions as ovarian source tumors, the nature of the tumor was not clear, miss diagnosed 5 as ovarian malignancy or ovarian teratoma, 2 as subserous myoma of uterus/broad ligament myoma. Conclusion: Ultrasonic findings of OT are lack of specificity, easy to be missed when relative small OT coexisting with other large ovarian lesions, or misdiagnosed as subserous myoma of uterus, broad ligament myoma and other ovarian tumors.
