SPREAD OF MALIGNANT OVARIAN TUMORS

Malignant ovarian tumors spread by local extension, lymphatic, hematogenous, and transcoelomic routes. Ovarian tumors are traditionally staged by laparoscopy utilizing the FIGO staging system (2). From the imaging aspects, the general principles are tabulated below.

Stage


I


II


III


IV
Criteria


Tumor limited to one or both ovaries

Tumor extension beyond ovaries but confined to pelvis (including mets to pelvic peritoneum only)

Regional lymphatic spread (para-aortic, iliac, inguinal) and/or extrapelvic peritoneal disease (omental caking, peritoneal nodules, hepatic capsular metastases)

Distant mets (lung, pleura, kidney, bone, hepatic parenchyma) and/or lym
