Purpose or Case Report: Overview:
Although rare, with only about 100 de novo cases reported a year, hepatoblastoma is the most common primary pediatric liver tumor in children under 3 years of age. The imaging findings of hepatoblastoma can be difficult to identify, especially for trainees, since not many radiologists have the opportunity to diagnose patients with this condition. Additionally, given the high rate of metastases, often to the skeletal system, at the time of diagnosis there is overlap with findings of non-accidental trauma. Treatment for hepatoblastoma requires specialized teams and prompt diagnosis with appropriate referrals resulting in improved management and prognosis. In this educational exhibit we review a de novo case of hepatoblastoma diagnosed at The University of New Mexico, with a focus on essential ultrasound, CT and MRI findings. Additionally, we will discuss associated gene mutations and congenital disorders, common sites of metastasis and how to use the PRETEXT method to risk stratify and guide management.

Outline:
Overview of hepatoblastoma
Review gene mutations and congenital disorders associated with hepatoblastoma
Review important findings of hepatoblastoma on ultrasound, CT and MRI, using unique images obtained at the University of New Mexico
Discuss common sites of metastasis and how osseous metastases can raise concerns non-accidental trauma
Checklist of how to use PRETEXT and brief review of treatment options

Goals:
Improve understanding of hepatoblastoma
Provide radiologist, especially trainees, with the tools necessary to recognize hepatoblastoma across multiple imaging modalities
Discuss how radiologists can provide focused management recommendations for treatment teams
