Abstract:
Objective To explore the clinical characteristics and CT features of malignant ovarian germ cell tumor(MOGCT)in children.Methods The CT image features and clinical characteristics of 27 cases of MOGCT confirmed by postoperative pathology were retrospectively analyzed.Results There were 6 cases of dysgerminoma(DG)(22.2%).The CT features were solid soft tissue masses with mild to moderate enhancement,"separate-like"enhancement within the mass,and thickened blood vessels around it.There were 8 cases of immature teratoma(IT)(29.7%).The CT features were mixed-density masses with soft tissue,fat,and calcifi-cation inside,and the solid part was significantly enhanced.There were 7 cases of yolk sac tumor(YST)(25.9%).The CT features were significantly enhanced,tortuous small blood vessels inside the mass,presenting a"bright spot sign".There were 3 cases of non-gestational choriocarcinoma(11.1%).The CT features were a low-density mass with large central necrosis,obvious enhance-ment after contrast,and thickened ovarian arteries and veins around it.There were 3 cases of mixed germ cell tumor(MGCT)(11.1%).The CT features were related to the tumor components.Conclusion MOGCT in children have their own CT characteristics.Combi-ning with the clinical manifestations of the children and serum tumor markers,qualitative diagnosis of the lesions can be made,which provides reliable help for the formulation of clinical diagnosis and treatment plans.
