Unexpected bone marrow uptake of thallium-201 in nonsecretory myeloma.
A 43-yr-old man was referred for any possible parathyroid abnormality that could explain his hypercalcemia and slightly increased parathormone levels. The thallium-technetium scan showed a diffuse abnormal thallium uptake incidentally in the bone marrow, otherwise parathyroid scan appearance was normal. He had an essentially normal bone scan, although subsequent nanocolloid scintigraphy demonstrated bone marrow expansion. Further investigations, including a bone marrow aspiration biopsy, confirmed the diagnosis of nonsecretory myeloma. This finding suggests that 201Tl imaging can be a useful tool to investigate those patients suffering from similar myeloid disorders causing bone marrow hyperplasia.
