Ovarian cystic neoplasms

Dr Owen Kang and Radswiki et al.

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 tumours <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 colour Doppler
  • associated ascites
  • associated regional lymphadenopathy
