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 ...
Suspicion of hepatomegaly indicates a thorough medical history and physical examination, wherein the latter typically includes an increased liver span. [citation needed] On abdominal ultrasonography, the liver can be measured by the maximum dimension on a sagittal plane view through the midclavicular line, which is normally up to 18 cm in ...
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.
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 ]
A medical condition is termed heterogeneous, or a heterogeneous disease, if it has several etiologies (root causes); as opposed to homogeneous conditions, which have the same root cause for all patients in a given group. Examples of heterogeneous conditions are hepatitis and diabetes. Heterogeneity is not unusual, as medical conditions are ...
Tumor characterization using the ultrasound method will be based on the following elements: consistency (solid, liquid, mixed), echogenicity, structure appearance (homogeneous or heterogeneous), delineation from adjacent liver parenchyma (capsular, imprecise), elasticity, posterior acoustic enhancement effect, the relation with neighboring ...
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 or excessive exposure to hepatotoxic pyrrolizidine alkaloids .
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.
