[Early differential diagnosis of tumors of the lesser pelvis using an appropriate combination of noninvasive and invasive methods].

One hundred and twenty-three female patients were subjected to ultrasound and CT examinations on account of suspected tumours in the area of the lesser pelvis, or to evaluate the postoperative situation. Twenty-five patients were subjected in addition to the mentioned examinations also to angiography of the pelvic arteries. From comparison of the results of the radiodiagnostic examination and the surgical (histological) diagnosis ensues that in patients with a malignant tumour of the ovaries and uterus and with a benign tumour of the uterus the CT examination gives-more satisfactory results than the ultrasound examination. In patients with a benign tumour of the ovaries ultrasonic and CT examinations were approximately equally satisfactory.
