Full history/Diagnosis is available below
CT demonstrated that a large heterogeneous enhancing mass within both lobes of the liver consistent with the patient's known diagnosis of hepatoblastoma.
Complete surgical resection of the tumor at diagnosis, followed by adjuvant chemotherapy, is associated with 100% survival rates, but the outlook remains poor in children with residual disease after initial resection, even if they receive aggressive adjuvant therapy.
Pathophysiology: Hepatoblastomas originate from immature liver precursor cells and present morphologic features that mimic normal liver development. Hepatoblastoma is usually unifocal and affects the right lobe of the liver more often than the left lobe.
Metastases affect the lungs and the porta hepatis; bone metastases occur very rarely. CNS involvement has been reported at diagnosis and during relapse.
