In people, the computed tomography (CT) characteristics of intrapelvic masses can be used to distinguish a malignant from a benign mass. As prognosis varies greatly between malignant and benign intrapelvic masses, knowledge of their biological behavior can aid treatment planning before surgery. The purpose of this study was to determine if CT characteristics exist to help differentiate benign from malignant intrapelvic masses in dogs. The CT images of 14 dogs with a histopathologically confirmed intrapelvic mass were evaluated. Postcontrast internal heterogeneity of the mass was the only characteristic significantly associated with malignancy (P=0.005). Preoperative CT examination of intrapelvic masses in dogs can provide prognostic information before invasive surgical treatment.
