CT of pelvic disorders in children.

The usefulness of computed tomography (CT) in evaluating benign and malignant pelvic mass was assessed in 17 children. By comparison with conventional radiography, CT provided supplementary diagnostic information in 29% of patients and more clearly defined the extent of lesions in 59%. In 47% of patients, the CT findings aided treatment planning. Unique diagnostic information was provided, especially in patients with benign disease, whereas delineation of the extent of disease and help in treatment planning occurred with both benign and malignant masses.
