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 ]
Benign liver tumors generally develop on normal or fatty liver, are single or multiple (generally paucilocular), have distinct delineation, with increased echogenity (hemangiomas, benign focal nodular hyperplasia) or absent, with posterior acoustic enhancement effect (cysts), have distinct delineation (hydatid cyst), lack of vascularization or show a characteristic circulatory pattern ...
Liver cancer, also known as hepatic cancer, ... and this is the reason why Thailand has particularly high rates of this cancer. [47] Choledochal cysts, ...
Bile duct cystadenoma (8161) or biliary cystadenoma is a slow-growing tumour arising from bile ducts of the liver. The presence of endocrine cells in the tumour also indicates its origin from the glands surrounding the bile ducts.
Biliary cystadenoma and cystadenocarcinoma constitute less than 5% of intrahepatic cysts originating from the bile duct. [6] Cystadenomas in liver are often confused with hydatid cyst as their appearance on various imaging techniques is nearly same. [7] Treating cystadenomas as hydatid cyst has resulted in recurrence of the cyst. [7]
Polycystic liver disease (PLD) usually describes the presence of multiple cysts scattered throughout normal liver tissue. [1] PLD is commonly seen in association with autosomal-dominant polycystic kidney disease, with a prevalence of 1 in 400 to 1000, and accounts for 8–10% of all cases of end-stage renal disease. [2]
Micrograph of an intrahepatic, i.e. in the liver, cholangiocarcinoma (right of image); benign hepatocytes are seen (left of image). Histologically, this is a cholangiocarcinoma as (1) atypical bile duct-like cells (left of image) extend from the tumor in an interlobular septum (the normal anatomical location of bile ducts), and (2) the tumor ...
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.
