Abstract:
:The magnetic resonance imaging (MRI) findings in 2 cases of ovarian cancer arising in an endometrioma are presented. In both cases, the cancer was evident as an enhancing mass within a blood-filled adnexal cyst. The MRI findings of an enhancing mass within a blood-filled adnexal cyst should prompt consideration of ovarian cancer arising in an endometrioma, facilitating recognition of a superimposed malignancy and potentially allowing for earlier and more efficacious treatment.
