Magnetic resonance imaging with liver-specific contrast agent in primary amyloidosis and intrahepatic cholestasis

Acta Radiol. 2007 Mar;48(2):145-9. doi: 10.1080/02841850601128959.

Abstract

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.
