ABSTRACT
Evaluation of pediatric liver lesions differs fundamentally from that in adults and requires a thorough, systematic approach that accounts for anatomical variations, congenital anomalies, and age-specific lesion profiles. Accurate diagnosis relies not only on imaging findings but also on clinical context, including pre-existing conditions, risk factors, and serum alpha-fetoprotein levels. Ultrasonography is the first-line imaging modality due to its wide availability and lack of ionizing radiation. Computed tomography and magnetic resonance imaging provide high-resolution characterization of lesion architecture, enhancement patterns, and overall hepatic anatomy. The PRE-TEXT system is commonly used to stage primary malignant pediatric liver tumors. It considers the number of involved hepatic segments and the tumor’s relationship to critical structures to guide surgical planning. Together with the POST-TEXT system used in post-operative follow-up, it serves as an important prognostic indicator for overall survival.
