They are, in most cases, located in the right hepatic lobe and are frequently seen as a single lesion. [7] Their size ranges from 1 to 30 cm. [7] They can be difficult to diagnosis with imaging studies alone, because it can be hard to tell the difference between hepatocellular adenoma, focal nodular hyperplasia, and hepatocellular carcinoma.

proper hepatic artery (entering) hepatic portal vein (entering) The hepatic duct lies in front and to the right, the hepatic artery to the left, and the portal vein behind and between the duct and artery. It also transmits nerves and lymphatics. Sympathetic nerves - these provide afferent pain impulses from the liver and gall bladder to the brain.
Liver tumor types by relative incidence in adults in the United States, with hepatoblastoma at right [4] Hepatoblastomas originate from immature liver precursor cells, are typically unifocal, affect the right lobe of the liver more often than the left lobe, and can metastasize. They are categorized into two types: "Epithelial Type" and "Mixed ...
The most frequent forms are metastatic malignant neoplasm of liver) liver cell carcinoma hepatocellular carcinoma; hepatoma; cholangiocarcinoma; hepatoblastoma; angiosarcoma of liver; Kupffer cell sarcoma; other sarcomas of liver; Benign neoplasm of liver include hepatic hemangiomas, hepatic adenomas, and focal nodular hyperplasia (FNH).
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.
Hepatic hemangioma (2D). The lesion is located in the left hepatic lobe. Note precise delineation, their increased echogenity and the heterogeneous internal structure. [citation needed] Hepatic hemangioma (CEUS). Progression of CA from the periphery toward the center of the lesion is evidenced by examination at various time intervals (a ...
Posterior abdominal wall, after removal of the peritoneum, showing kidneys, suprarenal capsules, and great vessels. (Hepatic veins labeled at center top.) Any obstruction of the venous vasculature of the liver is referred to as Budd–Chiari syndrome, [19] from the venules to the right atrium. This leads to increased portal vein and hepatic ...
Visceral nodes of the abdominal cavity. The hepatic lymph nodes consist of the following groups: (a) hepatic, on the stem of the hepatic artery, and extending upward along the common bile duct, between the two layers of the lesser omentum, as far as the porta hepatis; the cystic gland, a member of this group, is placed near the neck of the gall-bladder;
