Multifocal liver lesions are encountered regularly in children and adolescents. By knowing the specific ultrasonographic, computed tomographic, and magnetic resonance imaging (MRI) features of benign and malignant pediatric liver lesions as well as the particular clinical setting, radiologists can frequently narrow the differential diagnosis and sometimes offer a definitive diagnosis. The purpose of this review article is to illustrate the imaging findings of numerous benign and malignant causes of multifocal liver lesions in the pediatric population.
