Renal uptake of 67Ga-citrate in renal amyloidosis due to familiar Mediterranean fever.

Renal uptake of 67Ga-citrate is described in a patient with biopsy-proven amyloidosis of the kidneys, due to Familiar Mediterranean Fever. After administration 150 MBq (4 mCi) 67Ga-citrate, scans were done at 48, 72, and 120 h. Intense uptake was noted in both kidneys. A renal biopsy done 5 days after the 67Ga-citrate scan revealed a pattern typical of amyloidosis. Gallium scanning can be useful in patients with fever of unknown origin. Renal amyloidosis can be considered when renal uptake of 67Ga-citrate associated with nephrotic syndrome is observed.
