Significance: The age of the patient is often a helpful clue in investigating the cause of the abdominal mass. In neonates, the most common origin of abdominal masses is the genitourinary system (cystic kidney disease, hydronephrosis). In infants and preschool-aged children, the most common malignant tumors are Wilms tumor and neuroblastoma. In adolescent-aged girls, ovarian disorders, hematocolpos, and pregnancy are more common causes of abdominal masses.
