Hepatoblastoma is a malignant liver cancer occurring in infants and children and composed of tissue resembling fetal liver cells, mature liver cells, or bile duct cells. They usually present with an abdominal mass. The disease is most commonly diagnosed during a child's first three years of life. [1]
Liver tumors can be classified as benign (non-cancerous) or malignant (cancerous) growths. They may be discovered on medical imaging (even for a different reason than the cancer itself), and the diagnosis is often confirmed with liver biopsy. [2] Signs and symptoms of liver masses vary from being asymptomatic to patients presenting with an ...
Abdominal ultrasonography of the liver, as a sagittal plane through the midclavicular line, with some standard measurements [2] Right lobe of the liver at the midclavicular line at ages 0 to 7 [16] Suspicion of hepatomegaly indicates a thorough medical history and physical examination , wherein the latter typically includes an increased liver ...
When imaging the liver with ultrasound, large lesions are likely to be HCC (e.g., a mass greater than 2 cm has more than 95% chance of being HCC).Given the blood flow to the liver, HCC would be most visible when the contrast flows through the arteries of the liver (also called the arterial phase) rather than when the contrast flows through the ...
Health officials remain perplexed by mysterious cases of severe liver damage in hundreds of young children around the world. The best available evidence points to a fairly common stomach bug that ...
A cavernous liver hemangioma or hepatic hemangioma is a benign tumor of the liver composed of large vascular spaces lined by monolayer hepatic endothelial cells. It is the most common benign liver tumour, and is usually asymptomatic and diagnosed incidentally on radiological imaging or during laparotomy for other intra-abdominal issues.
Chronic liver disease is rare in children and adolescents; however, congenital liver disorders are associated with an increased the chance of developing HCC. [21] Specifically, children with biliary atresia, infantile cholestasis, glycogen-storage diseases, and other cirrhotic diseases of the liver are predisposed to developing HCC in childhood.
Cavernous hemangiomas are erroneously called the most common benign tumors of the liver. [14] Usually one malformation exists, but multiple lesions can occur in the left or right lobe of the liver in 40% of patients. [3] Their sizes can range from a few millimeters to 20 centimetres. Those over 5 cm are often referred to as giant hemangiomas. [3]
