CEUS in paediatric hepatic lesions

Focal liver lesions (FLL) are commonly observed in adult patients and rarely reported in children. The reasons for this remain speculative and the exact data concerning the incidence of these lesions in childhood are lacking. Primary hepatic tumors are a diverse group of epithelial and mesenchymal tumors accounting for 0.5 and 2.0% of all pediatric neoplasms. Focal liver lesions in children can be benign, malignant, or indeterminate. About one-third of the pediatric primary liver masses are benign. In pediatric patients, most benign focal liver lesions are inborn and may grow like the rest of the body. Knowledge of pediatric liver diseases and their imaging appearances is essential in order to make an appropriate differential diagnosis. Selection of the appropriate imaging test is challenging, since it depends on a number of age-related factors. The presentation will focus on the most frequently encountered benign and malignant liver tumors in children (infantile hepatic hemangioendothelioma, mesenchymal hamartoma, focal nodular hyperplasia, nodular regenerative hyperplasia, and hepatocellular adenoma, hepatocellular carcinoma and metastases) .
