    Summary

    This study reviews 50 hepatoblastoma cases in young children, finding characteristic calcification patterns and imaging features. These findings aid in differentiating hepatoblastoma from other pediatric liver tumors.

    Area of Science:

    • Pediatric Oncology
    • Diagnostic Imaging
    • Hepatobiliary Diseases

    Background:

    • Hepatoblastoma is a rare but significant liver cancer in infants and young children.
    • Accurate diagnosis and differentiation from other liver neoplasms are crucial for effective management.

    Purpose of the Study:

    • To analyze imaging findings in pediatric hepatoblastoma cases.
    • To identify characteristic features that can aid in differentiating hepatoblastoma from other liver tumors in children.

    Main Methods:

    • Retrospective review of 50 hepatoblastoma cases.
    • Analysis of radiographic, angiographic, sonographic, and computed tomography (CT) findings.
    • Correlation of imaging features with histological findings.

    Main Results:

    • Hepatoblastoma typically presents as hepatomegaly or a mass in infants and young children.
    • Radiographs showed calcification in 11/20 cases, often as small chunks correlating with osteoid formation.
    • Angiography revealed tumor vascularity, sonography showed nodularity/lobulation, and CT demonstrated hypodense, lobulated masses.

    Conclusions:

    • Specific calcification patterns (small chunks) and imaging features like tumor lobulation on sonography or CT can help differentiate hepatoblastoma.
    • These findings are valuable for early and accurate diagnosis in pediatric patients under 5 years of age.
