Ruptured hemorrhagic copus luteal cyst
Right adenexa is a heterogenous mass with a curvilinear area of enhancement that is discontinuous medially.
There is also a focus of active arterial extravasation. Free fluid, consistent with blood, is seen in the pelvis tracking up to Morison's pouch and around the spleen.
Infiltration of the omentum is demonstrated.
