Granulosa cell tumors of the ovary are a type of sex cord / stromal ovarian tumor.
It can be divided into two broad subtypes:
adult granulosa cell tumor of the ovary: much more common and accounts for ~95% of cases 5
juvenile granulosa cell tumor of the ovary

Ovarian cystic neoplasms
Ovarian cystic neoplasms can be either benign or malignant and can arise from epithelial, stromal, or germ cell components. In general, the risk of malignancy in unilocular cystic tumors <10 cm in women over the age of 50 years is thought to be low 3,4.

MRI reporting guidelines for cervical cancer
MRI reporting guidelines for cervical cancer help maintain uniformity of reports and assessment of important imaging staging criteria.
Tumor size
The tumor should be measured in three orthogonal planes. Tumors with a maximum diameter >4 cm are usually not amenable to primary radical surgery.
