Unusual Pelvic Masses: A Comparison of Computed Tomographic Scanning and Ultrasonography

Abstract

Four unusual [malignant] pelvic masses, studied by CT [computed tomography] and gray scale ultrasonography, demonstrate the comparative values of these modalities for this area of the [human] body. In each instance a significant contribution to the diagnosis was made by 1 or both techniques. The ultrasound study provides a somewhat better differentiation of solid from cystic lesions, but the CT scan denotes to best advantage the anatomy of the area, and provides a means of viewing bone as well as soft tissue detail.
