Ovarian cystic neoplasms

Last revised by Ammar Ashraf on 10 Jun 2023

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


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
