From: MR imaging of ovarian masses: classification and differential diagnosis
Classification of adnexal masses basing on morphological appearance | ||
|---|---|---|
Cystic unilocular (benign) | non ovarian | paraovarian cysts, hydrosalpinx, pyosalpinx and hematosalpinx |
ovarian | functional cysts and serous cystadenomas (common) | |
cystadenofibromas and mucinous cystadenomas (less common) | ||
Cystic multilocular (benign and borderline) | endometriomas, mucinous cystadenomas and borderline tumours (common) | |
serous cystadenomas (less common) | ||
Cystic and solid (benign, borderline and malignant) | benign | mature cystic teratoma |
borderline to malignant | surface epithelial tumours, metastasis, Yolk sac, granulosa cell and Sertoli-Leydig tumours | |
Predominantly solid (benign, borderline and malignant) | benign | Brenner tumour, fibrothecomas |
borderline to malignant | serous and mucinous carcinomas, dysgerminoma and Yolk sac tumour, granulosa and Sertoli-Leydig cell tumours, metastasis | |
