There are multifocal areas of ground-glass opacities involving all lung lobes associated with bibasilar increased reticulations.
Case Discussion
This case shows the non-specific pattern of interstitial pneumonia and pulmonary fibrosis, due to the inhalation of the hard metal (cobalt or cobalt alloys e.g. tungsten).

Biopsy shows giant cell interstitial pneumonia.
