Magnetic resonance imaging with liver-specific contrast agent in primary amyloidosis and intrahepatic cholestasis.
Magnetic resonance imaging (MRI) findings in hepatic amyloidosis are not well defined. Here, we report on a patient with renal failure caused by primary amyloidosis (AL type) who developed jaundice. Ultrasound and computed tomography were normal except for some ascites. MRI with oral manganese-containing contrast agent revealed several focal areas without contrast uptake in the hepatocytes and no bile secretion after 8 hours. No extrahepatic bile obstructions were found. Liver biopsy showed severe intraportal, vascular, and parenchymal amyloidosis causing severe cholestasis and atrophy of hepatocytes.
