Discussion
US and CT findings (pelvic mass with mixed parenchimal structure,
presence of internal and irregular septa, marked enhancement
of septa and solid portion), suggest hypotesis of ovarian
cystoadenocarcinoma.
Among the gynecologic malignancies, ovarian cancer is the
second most common in incidence (1). As most patients
presents with advanced disease, the prognosis is poor.
Five year survival is only 41% for all stages (2).
Both MR and CT can be helpful adjunct in the treatment
planning of ovarian cancer. Several studies have addressed
the value of CT in the preoperative management of ovarian
tumor with reported accuracies of 77%; staging accuracy for
MR imaging was similar 78% (3). Detection of peritoneal
implants on CT and MR has been studied extensively and both
modalities had limitation in detection of implant lesion
smaller than 10 mm and localized on bowel surface, mesentery
and peritoneum (3). MR now seems to be superior to in the
evaluation of local extention of the tumor and in the
definition of implants with possible involvment of the
hemidiaphragma and liver surface.
However cross sectional imaging provides paramount
information for surgical and management planning
