Bone scan in a case of amyloidosis.

A 49-year-old woman was diagnosed as having multiple myeloma and tuberculosis of the spine (Pott's disease) in 1973. In 1975, she complained of skin nodules in her lower extremities. Biopsy showed that these were amyloid nodules. A bone scan in 1978 showed accumulation of Tc-99m-MDP in the nodules. To our knowledge, this finding has not been previously described.
