Abstract: Objective To study the value of multislice spiral computed tomography (CT) in the diagnosis of ovarian fibroma. Method The CT findings of 9 cases with pathologically confirmed ovarian fibroma were retrospectively analyzed by two radiologists. Results All of the 9 cases showed unilateral adnexal mass with demarcated boundary. There were three different types of ovarian fibroma according to the CT appearancessimple type(n=4), degeneration type(n=3) and the ovarian fibroma with ascites(n=2). The simple type showed homogeneous-density solid tumor with no enhancement; two of them diagnosed as uterine leiomyomas and the other two as benign tumor originated from the ovary. The degeneration type showed irregular or round hypodensity inside the tumor with no enhancement; one of them was diagnosed as malignant tumor and the other two as intrapelvic mass. The ovarian fibroma with ascites showed homogeneous density with no enhancement; one with ascites and pelvic effusion and the other one with pleural effusion, ascites and pelvic effusion, both of whom were diagnosed as malignant tumor that possibly originated from the ovary. Conclusions The ovarian fibroma has diverse CT findings. They often appear as a unilateral adnexal solid tumor without obvious enhancement. A diagnosis of Meigs's syndrome may be made when it is accompanied with ascites and pleural effusion.
