Systemic amyloidosis of amyloid light chain associated protein (AL), also called primary amyloidosis, frequently involves the liver, but rarely causes clinically apparent liver disease. The more common presentation is with acute renal failure. Hepatomegaly and mild elevation of alkaline phosphatase are the most common clinical and biochemical findings, respectively. We report a case of systemic...

BACKGROUND AND AIMS The liver is frequently involved in amyloidosis but the significance of hepatic amyloid has not been systematically studied. We have previously developed scintigraphy with 123I serum amyloid P component (123I-SAP) to identify and monitor amyloid deposits quantitatively in vivo and we report here our findings in hepatic amyloidosis. METHODS Between 1988 and 1995, 805 patien...

A 54-year-old man with polycystic liver disease received a domino liver transplantation (DLT) from a patient of hereditary ATTR amyloidosis with the transthyretin Ser50Arg mutation. Ten years after transplantation, he felt a slight numbness in his toes, and cardiac amyloidosis was simultaneously suspected upon a heart function evaluation. Biopsy specimens from the myocardium revealed transthyre...

Hepatic amyloidosis is a rare disease that presents as an infiltrative disease involving liver. Amyloidosis is a systemic disease characterized by the extracellular deposition of amyloid protein in many organs. Progressive organ involvement leads to organ malfunction and death usually resulting from renal and/or cardiac involvement. Liver and spleen are major sites of involvement. The wide rang...

Amyloidosis is classified according to the distribution pattern of amyloid deposition sites and associated diseases. Hepatic amyloidosis is not infrequent, although rarely causes clinical liver disease. We report two cases of amyloidosis diagnosed by liver biopsy. One presented with symptoms related almost to the liver disease, such as jaundice, hepatomegaly and indigestion. Echocardiogram reve...

Amyloidosis is characterised by the accumulation of poorly soluble fibrous proteins in the extracellular space of various bodily organs. Light chain amyloidosis (AL) is recognised as the most common form of systemic amyloidosis. Light chains are deposited in the majority of bodily organs, and accumulation of them in the liver produces hepatomegaly. We report a case of AL-systemic amyloidosis wi...

Systemic amyloidosis was induced consistently in mice by intramuscular injection of syngeneic organ (liver and kidney) extracts mixed with CFA six times at weekly intervals. Syngeneic organ extract with CFA also induced amyloidosis of a lesser degree. All three strains of mice (C57BL/6, C3H/He, and BALB/c) injected with a syngeneic liver extract mixed with CFA developed systemic amyloidosis; th...

Hepatic involvement of amyloidosis is common. Diffuse infiltration with hepatomegaly is a usual radiologic finding of hepatic amyloidosis. To our knowledge, this is the first case of amyloidosis involving the liver that presented as a mass.

Amyloidosis is characterized by the deposition of extracellular protein material, amyloid, in various organs. The clinical and imaging features of the disease are often nonspecific and a tissue biopsy is often required. We present the case of a 64-year-old man with biopsy proven amyloidosis of the liver. The patient presented with non-specific clinical symptoms. Routine imaging showed hepatomeg...
