False-positive liver scan in a patient with hepatic amyloidosis: case report

A case of secondary hepatic amyloidosis exhibiting a large liver and multiple defects on the radiocolloid scintigraph is presented. Biopsy and angiographic studies indicated that the areas of reduced colloid uptake represented heavy amyloid deposition, and the area of the left lobe with contrasting high activity most probably represented compensatory hypertrophy.
