Which vascular tumor is the most common symptomatic hepatic tumor in infancy?

• A. Hemangioendothelioma
• B. Hepatoblastoma
• C. Angiosarcoma
• D. Hepatic Adenoma

Answer: (A)

In infancy, a vascular tumor of the liver that most commonly causes symptoms is a hemangioendothelioma. This lesion is a proliferation of abnormal blood vessels lined by endothelium, and it tends to be present early in life with enough vascularity to produce signs such as hepatomegaly, anemia, or even high-output heart failure when large. On ultrasound, you’d expect a well-defined, highly vascular mass with multiple feeding arteries on color Doppler, reflecting its network of vascular channels. These tumors can be focal, multifocal, or diffuse and may involute over time, though symptoms prompt treatment in more significant cases. Other hepatic tumors in children, like hepatoblastoma, are malignant and not primarily vascular lesions seen as the most common symptomatic liver tumor in infancy; angiosarcoma is rare in this age group; hepatic adenoma is typically an adult entity associated with hormonal factors and is uncommon in infants.
