Pelvic neoplasms can arise from the genitourinary tract, gonads, soft tissues, or bone. The role of imaging is to confirm the presence of tumor, determine the site of origin, delineate the extent for staging and treatment planning, and serve as a baseline for monitoring response to therapy. MR imaging is well suited for the characterization and staging of pediatric pelvic tumors. This article reviews the imaging findings and staging evaluation of the common nongynecologic neoplasms in children. Prostatic, bladder, gonadal, and sacrococcygeal tumors are discussed. Gynecologic tumors are discussed elsewhere in this issue.
盆腔肿瘤可起源于泌尿生殖道、性腺、软组织或骨骼。影像学检查的作用是确认肿瘤的存在，确定肿瘤的起源部位，描绘肿瘤范围以进行分期和治疗规划，并作为监测治疗反应的基线。磁共振成像（MR成像）非常适合小儿盆腔肿瘤的特征描述和分期。本文综述了儿童常见非妇科肿瘤的影像学表现及分期评估。文中讨论了前列腺、膀胱、性腺及骶尾部肿瘤。妇科肿瘤在本期其他部分讨论。
