Amyloidosis: a rare cause of severe acute liver failure

Gastrointestinal amyloidosis can be primary, more associated with monoclonal plasma cell dyscrasia, or secondary, usually secondary to a tissue-destructive, chronic inflammatory process (such as inflammatory bowel disease, for example) and long-term dialysis. The rare presentation of severe acute liver failure in systemic amyloidosis can make this diagnosis/ management more difficult. Hepatomegaly with signs of diffuse infiltrative disease and periportal involvement associated with thoracic and other abdominal radiological findings in the appropriate clinical context may constitute a diagnostic imaging clue in this challenge.
