Oncology. 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.
Hepatomegaly is enlargement of the liver. [4] It is a non-specific medical sign, having many causes, which can broadly be broken down into infection, hepatic tumours, and metabolic disorder. Often, hepatomegaly presents as an abdominal mass. Depending on the cause, it may sometimes present along with jaundice. [1]
Liver cell death and severe lactic acidosis may be present as well. Caudate lobe enlargement is often present. The majority of patients have a slower-onset form of Budd–Chiari syndrome. This can be painless. A system of venous collaterals may form around the occlusion which may be seen on imaging as a "spider's web".
The liver is divided into four lobes. This image shows the large right lobe and a smaller left lobe separated by the falciform ligament. 1: Right lobe of liver. 2: Left lobe of liver. 3: Quadrate lobe of liver. 4: Round ligament of liver. 5: Falciform ligament. 6: Caudate lobe of liver. 7: Inferior vena cava.
Ultrasonography of liver tumors involves two stages: detection and characterization. [1] Tumor detection is based on the performance of the method and should include morphometric information (three axes dimensions, volume) and topographic information (number, location specifying liver segment and lobe/lobes). The specification of these data is ...
Other suggestive findings are an enlarged caudate lobe, liver surface nodularity [63] widening of the fissures and enlargement of the spleen. [64] An enlarged spleen , which normally measures less than 11–12 cm (4.3–4.7 in) in adults, may suggest underlying portal hypertension . [ 65 ]
10-20%. Hepatic veno-occlusive disease (VOD) or veno-occlusive disease with immunodeficiency is a potentially life-threatening condition in which some of the small veins in the liver are obstructed. It is a complication of high-dose chemotherapy given before a bone marrow transplant and/or excessive exposure to hepatotoxic pyrrolizidine alkaloids.
Hemangioma. A hemangioma or haemangioma is a usually benign vascular tumor derived from blood vessel cell types. The most common form, seen in infants, is an infantile hemangioma, known colloquially as a "strawberry mark", most commonly presenting on the skin at birth or in the first weeks of life. A hemangioma can occur anywhere on the body ...
