Primary diagnosis of gynecological tumors by ultrasonography and computed tomography

In 33 patients with a pelvic mass or otherwise suspected to have gynecological malignancy, ultrasonography and computed tomography of the abdomen were performed. The results were compared afterward with the findings at operation. With both methods the nature of the tumor had been predicted correctly in the majority of cases. Localization and metastases were more frequently detected by computed tomography. Both tests appeared, in a way, to be complementary. There were no false-negative findings in both sonography and computed tomography. In three cases false-positive results were seen with both techniques.
