Pediatric malignant liver tumors are rare, some of which occur only in children but that are similar to those that occur in adults.
Malignant liver tumors account for ~1% of pediatric malignancies 2.
Broadly, any malignant liver mass can be defined as a metastasis or primary liver tumor. The commonest source of pediatric liver metastases is neuroblastoma 1.
Primary malignant hepatic neoplasms in children can broadly be classified by their cell of origin 1:
- epithelial (hepatocyte-derived)
An understanding of the clinicopathologic features of these neoplasms and how these features affect their imaging appearance helps the radiologist offer an appropriate differential diagnosis for a child with a liver mass.
