most common benign hepatic tumor in childhood
|
Hepatic hemangioma is the most common benign hepatic tumor in childhood and is nearly always (85%) diagnosed within the first 6 months of life. It may present with heart failure, and it regresses with time as with other hemangiomas. The imaging characteristics on ultrasound are of single or multiple solid masses of varying echogenicity, often containing linear foci of calcification. Doppler sonography shows blood flow in multiple tortuous vessels within the mass. They are associated with enlargement of the hepatic artery and celiac trunk and marked diminution of the caliber of the aorta distal to the celiac trunk.
|
|
most common primary malignant hepatic neoplasm to present in the neonatal period
|
Hepatoblastoma is the most common primary malignant hepatic neoplasm to present in the neonatal period, with 65% occurring under the age of 2 years. It accounts for approximately 1% of pediatric cancers with an incidence of 1.5 per million. Typical imaging features on ultrasound are those of a poorly marginated solitary mass of mixed echogenicity. It may contain calcification, necrosis, or hemorrhage. Doppler examination may reveal evidence of vessel invasion and malignant neovascularity.
