[Pediatric liver tumor: What to do?]

Area of Science:

• Pediatric Radiology
• Pediatric Oncology
• Hepatology

Context:

• Two-thirds of pediatric liver tumors are malignant, necessitating accurate differentiation from benign pseudotumors like abscesses or hematomas.
• Pediatricians are often the first to encounter hepatic masses in children, requiring age-stratified diagnostic considerations.

Purpose:

• To outline the age-dependent diagnostic strategies for pediatric hepatic masses.
• To highlight key laboratory findings and imaging modalities for evaluating pediatric liver lesions.
• To emphasize the importance of multidisciplinary referral for definitive diagnosis and management.

Summary:

• Diagnostic approaches for pediatric liver masses vary by age, with hepatoblastoma and hemangioma common before age three, and hepatocarcinoma, sarcoma, focal nodular hyperplasia, and adenoma more frequent in older children.
• Key laboratory tests include alpha-fetoprotein, beta-hCG, and urinary catecholamines, while ultrasonography serves as the primary imaging modality.
• Further characterization with CT or MRI, guided by clinical status and equipment availability, is essential for diagnosis and management by specialized pediatric oncology, surgery, and radiology teams.

Impact:

• Facilitates timely and accurate diagnosis of pediatric liver masses, improving patient outcomes.
• Provides a framework for pediatricians to initiate appropriate diagnostic workups for suspected hepatic lesions.
• Guides the selection of advanced imaging techniques for definitive diagnosis and treatment planning in pediatric liver tumors.
