Abstract:
Objective To observe clinical characteristics and ultrasonic manifestations of ovarian dysgerminoma.Methods Clinical and ultrasonic data of 35 patients with surgically and pathologically confirmed ovarian dysgerminoma were retrospectively analyzed.Results The mean age of 35 patients was(23.3±9.4)years.Predominant clinical manifestations of ovarian dysgerminoma included pelvic mass(30/35,85.71％),menstrual irregularities(9/35,25.71％)and abdominal pain(7/35,20.00％),7 cases(7/35,20.00％)were found with gonadal dysgenesis.Elevated serum human chorionic gonadotropin(HCG)level and carbohydrate antigen 125 level were observed in 96.00％and 83.33％cases,respectively.The lesions mainly present as unilateral(right-sided),large(mean maximum diameter of[11.60±4.98]cm),lobulated(67.57％)and well-defined(72.97％)solid mass,with internal lobular structures(64.86％)and cord-like septations(62.16％).CDFI revealed abundant blood flow(predominantly grade 3)with low resistance index(mean 0.44±0.11).Conclusion Ovarian dysgerminoma predominantly occurred in young women,typically presented as a large unilateral solid mass,with characteristic fibrovascular septa and abundant low-resistance blood flow showed on ultrasound.
