Hepatoblastoma: case report and literature review.

Hepatoblastoma is the most common primary malignant hepatic neoplasm in children and must be differentiated from other hepatic tumors such as hepatocellular carcinoma, metastatic neuroblastoma, hemangioendothelioma, and mesenchymal hamartoma. A case report of hepatoblastoma with its attendant radiologic findings is presented. Because the prognosis is dependent on whether the tumor is surgically resectable, the accurate radiologic evaluation of patients with hepatoblastoma is critical. The roles of plain film radiography, ultrasound, computed tomography, and angiography in the evaluation of pediatric hepatic neoplasms are discussed.
