Some abdominal masses are diagnosed by prenatal sonography. Although the majority of these masses are benign and represent organomegaly, there are serious and life-threatening diagnoses that require prompt diagnosis and treatment. The underlying causes of abdominal masses in the pediatric population include vascular, infectious, inflammatory, neoplastic, and congenital. Table 383-1 lists possible diagnoses by location of origin and age group.
