Bone scintigraphy in the diagnosis of pulmonary calcification in multiple myeloma.

We present a case of multiple myeloma in which pulmonary calcification was clinically shown by bone scintigraphy and subsequently confirmed at autopsy. It is suggested that, in patients with myeloma, radionuclide bone scanning may be of value for differentiating deposits in the lung due to calcification from those due to other types of pulmonary infiltration revealed by chest X-rays. A thorough review of the relevant literature is presented.
