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.
Radiographic features
Ultrasound
If a cystic lesion is detected, concern for an ovarian cystic neoplasm is raised when a cyst is large, or if there are complex features, including:
- thick septations: >3 mm
- papillary projections
- mural nodules
- frank solid components
- increased vascularity on color Doppler
- associated ascites
- associated regional lymphadenopathy
