Bone scan showed greatly increased
accumulation of radioactivity diffusely throughout the
lungs as an incidental finding. Serum calcium and phosphorus
levels were within the normal ranges. CT scan of
the chest showed pleural effusion on the right side and
slightly disseminated micronodular density increase in
the right lung and disseminated micronodular interstitial
infiltrations in the left lung. Percutaneous lung biopsies

data established the diagnosis of pulmonary WMG
