case_images: CT guided lung biopsy showed H&E (hematoxylin and eosin) and PAS (periodic acid-schiff) positive amorphous eosinophilic material suspicious for amyloid. Initial staining with congo red was negative. However, it stained positively with Thioflavin T stain and had weak green birefringence under polarized light.

case_images: CT guided lung biopsy showed H&E (hematoxylin and eosin) and PAS (periodic acid-schiff) positive amorphous eosinophilic material suspicious for amyloid (Figure 1).
case_images: Brain biopsy was positive for eosinophilic material (similar to the lungs) but negative for congo red and thioflavin T stain.
