Abstract：Objective: To analyze the ultrasonographic features of ovarian dysgerminoma and to explore the value of ultrasonography in the diagnosis of ovarian dysgerminoma. Methods: The ultrasonographic features of 21 cases of ovarian dysgerminoma confirmed by operation and pathology in the First Affiliated Hospital of Wenzhou Medical University and the Second Affiliated Hospital of Wenzhou Medical University from January 2009 to June 2020 were retrospectively analyzed. The location, size, shape, boundary, internal echo and blood flow of the tumor were summarized. Results: The age of 21 patients with ovarian dysgerminoma was 13-64 years old, aged (20.8±8.6) in average. Ultrasonography showed that the adnexal area was mainly solid with clear boundary. All the masses were single and large, and 16 cases were lobulated. The internal echo was uneven, with “fibrous vascular septum” and lobular structure seen in 16 cases. In addition, there were necrotic cystic anechoic areas in 10 cases. There was abundant low resistance blood flow in the interior, with blood flow signal of grade III in 18 cases, grade II in 2 cases and grade I in only 1 case. Conclusion: The ultrasonographic manifestations of ovarian dysgerminoma have shown certain characteristics, and the combination with some clinical biochemical indexes is helpful to improve the diagnostic accuracy of the tumor.
