Diagnosis, histopathologic correlation and management of hepatoblastoma: What the radiologist needs to know

Abstract

Hepatoblastomas are complex pediatric tumors with several pathological subtypes, some of which demonstrate differing imaging features and portend varying prognosis. The radiologist plays a major role not only in the pre-surgical evaluation and baseline staging of the tumor, but also in guiding management and evaluating prognosis based on the PRETEXT (pretreatment extent of tumor) classification. We discuss the pathology, imaging features, and baseline evaluation, with a focus on the role of the radiologist in the management of these tumors.
