Endometrioma

Discussion:

This case shows classic appearance of endometrioma vs hemorrhagic cyst.

The radiologist can try able to differentiate these two entities on MRI by the following features:

  • endometriotic cyst
    • T2 shading sign
    • persistent signal on  fat saturated images
    • variable restriction on DWI/ADC images
  • hemorrhagic cyst
    • T2 hyperintense
    • signal loss on fat saturated images
    • no restriction on DWI/ADC images.
