In some cases this accumulation can mimic a liver tumor. Sometimes the opposite phenomenon can be seen, that is an "island" of normal parenchyma in a “shining” liver. In both cases ultrasound examination identifies a well defined, un-encapsulated area, with echostructure and vasculature similar to those of normal liver parenchyma.
Calcification is the accumulation of calcium salts in a body tissue. It normally occurs in the formation of bone, but calcium can be deposited abnormally in soft tissue, [1] [2] causing it to harden. Calcifications may be classified on whether there is mineral balance or not, and the location of the calcification. [3]
Abdominal ultrasound can reveal hepatosplenomegaly, ascites, renal echogenicity and diffused arterial calcifications involving the aorta, common iliac, splenic, and renal arteries, as well as peritoneal calcifications involving the visceral peritoneum overlying the liver and intestine; Brain ultrasound can show dilated lateral ventricles ...
An ultrasound examination shows accumulation of chalky material (calcification) in the adrenal gland in about half of infants with LAL-D. [2] [4] Complications of LAL-D progress over time, eventually leading to life-threatening problems such as extremely low levels of circulating red blood cells (severe anemia), liver dysfunction or failure ...
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.
Dystrophic calcification (DC) is the calcification occurring in degenerated or necrotic tissue, as in hyalinized scars, degenerated foci in leiomyomas, and caseous nodules. This occurs as a reaction to tissue damage, [ 1 ] including as a consequence of medical device implantation.
Ultrasound of malformed vessels within the fibrous scar of focal nodular hyperplasia. Liver tumor types by relative incidence in adults in the United States, with focal nodular hyperplasia at right. [3] Focal nodular hyperplasia's most recognizable gross feature is a central stellate scar seen in 60–70% of cases.
In Bristol University's study Children of the 90s, 2.5% of 4,000 people born in 1991 and 1992 were found by ultrasound scanning at the age of 18 to have non-alcoholic fatty liver disease; five years later transient elastography found over 20% to have the fatty deposits on the liver of steatosis, indicating non-alcoholic fatty liver disease ...
