Tumors that develop within the liver may be either benign (noncancerous) or malignant (cancerous). Tumors can start in the liver, or spread to the liver from another cancer in the body. Malignant liver tumors have been reported to metastasize to other organs such as regional lymph nodes, lungs, kidneys, pancreas, spleen and others.
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 ...
Cancer in cats can occur in any location or body system, [3] and most symptoms can be detected externally. [2] While each type of cancer has its own distinctive symptoms, most indicate their presence by the occurrence and the prolonged presence of any common symptom. [1] Some of the general symptoms of cancer in cats are: [3]
Fatty liver disease (FLD), also known as hepatic steatosis and steatotic liver disease (SLD), is a condition where excess fat builds up in the liver. [1] Often there are no or few symptoms. [1] [2] Occasionally there may be tiredness or pain in the upper right side of the abdomen. [1] Complications may include cirrhosis, liver cancer, and ...
Feline hepatic lipidosis, also known as feline fatty liver syndrome, is one of the most common forms of liver disease of cats. [1] The disease officially has no known cause, though obesity is known to increase the risk. [2] The disease begins when the cat stops eating from a loss of appetite, forcing the liver to convert body fat into usable ...
The liver parenchyma is the functional tissue of the organ made up of around 80% of the liver volume as hepatocytes. The other main type of liver cells are non-parenchymal. Non-parenchymal cells constitute 40% of the total number of liver cells but only 6.5% of its volume. [11]
During ultrasound examinations, sometimes echogenicity is higher in certain parts of body. Fatty liver could cause increased echogenicity in the liver, especially if the liver transaminases are elevated. [3] Women with polycystic ovary syndrome may also show an increase in stromal echogenicity.
Human cases of opisthorchiasis may affect the liver, pancreas, and gall bladder. If not treated in the early stages, opisthorchiasis may cause cirrhosis of the liver and increased risk of liver cancer, but may be asymptomatic in children.
