Which imaging finding may be seen in hepatoblastoma?

• A. Cysts
• B. Calcifications
• C. Hypervascularity
• D. Hypoechoic margins

Answer: (B)

Calcifications inside the tumor are a recognized imaging feature of hepatoblastoma, especially in the pediatric liver. On ultrasound, these appear as bright echogenic foci with posterior acoustic shadowing within a heterogeneous mass. CT or MRI can show calcified specks or patches within the lesion. This finding helps distinguish hepatoblastoma from many other pediatric liver lesions, where calcifications are less common. While hypervascularity can also be seen in hepatoblastoma on Doppler, the presence of calcifications is a more characteristic clue for this tumor. Cysts would present as fluid-filled, typically anechoic areas, and hypoechoic margins are not specific to hepatoblastoma.
